The computing of end-bearing capacity of pile has vital significances for foundation design while the foundations analysis is usually problematic due to those diverse soils and engineering conditions. Though various CPT-based methods which have already been applied in numerous huge engineering practices are available for the analysis of pile foundation bearing capacity home and abroad, there still seemed lacking legitimate guidance assisting to select these formulations quite effectively. In this paper, five CPT-based design methods are compared in deep, the realization through computer program is also presented, with the capacity data accumulated from pile engineering coming into mind, we are on the way to making designers choose better methods during the designing process.

This paper deals with analysis of pecularities of design and strengthening of tapered, curved and pitched cambered glulam beams under action of lateral tension. The formulas and drawings presented give the possibility for addition and clarification of existed design methods of such beams in our country. For strengthening the apex zone of pitched cambered beams the author offers the way of precompression of the member according to the patent of Lithuanian Republic No 2045. By the use of this method it is possible to increase bearing capacity, fire resistance and durability of glulam bearing elements. The given method allows to simplify manufacturing of alike elements and to improve their technology. Another method (according to the patent of Lithuanian Republic No 2046) also gives the solution of the problem of setting inserts of any size and shape made of different materials. The inserts are used for joint constructions as well as for strengthening dangerous places. The method is carried out in the following way. The most strained parts of wooden bearing element are set and inserts are installed where needed. Corresponding grooves, usually longitudinal, are made before glueing separate planks. The planks having been glued into one piece, grooves of wanted size and shape are made. Inserts of different shape are set into package during its assemblage. In such cases inserts serve as additional plank package fixers. After that by means of pneumatic or hydraulic presses pressurization and final element treatment follows. Alongside of flat inserts another method of insert setting may be used: planks after corresponding grooves have been made are stowed into package and by means of diaphragm made of steel or any other like material are fixed into a position. Then pressurization by pneumatic or hydraulic presses, extraction of diaphragms out of grooves, setting of flat glued inserts into grooves follows. The given method may be applied at any glulam bearing elements plant. The usage of this glulam bearing element strengthening method assures the following advantages: the possibility of making grooves of any size and shape, as well as setting corresponding inserts into grooves which help to strengthen and connect the elements. It allows not only to increase the bearing capacity and durability, but also the fire resistance of the given element. The usage of nonmetallic inserts increase dielectricity or “ratio transparency” of structures.

The increasing number of residents in South Tangerang has an impact on increasing the need for lower housing. The development of vertical housing with the market name of flats, apartments and is the most effective anticipatory solution to overcome land prices which result in market limitations, especially for the upper middle class. This 32-storey apartment project uses a combined foundation system between drill pile foundation & raft foundation. With the combination of these two very massive systems, of course, it will have a very expensive cost to implement and take a long time to complete. In order to avoid cost overruns, the foundation design must look at the possibilities. To determine the efficiency of the combined system foundation design between pile bored foundation & raft foundation, the researchers analyzed the value of the bearing capacity and also the settlement that occurred in the existing foundation using the Poulos method, the equivalent Raft method and the Vesic method. From the results of the study, it was found that the contribution of the pile foundation bearing capacity was 24.10%. the placement of the raft foundation is 75.90% and the settlement analysis using the Poulos 8.95cm method, the 12.41cm Equivalent Raft method and the Vesic 12.1cm method, these three results are close to the maximum settlement limit.

The characteristical values of bearing capacity of silty soil are determined on different basis in Binzhou area, which causes a great difference in actual work. Based on engineering practices, most original data are counted and calculated for standard penetration test, soil test and double bridge CPT (cone penetration test). The result shows that the bearing capacity is more accurate as concluded by in-situ test data, and also can provide a more helpful method for foundation design, which will play an active role in undertaking the specific engineering investigation work and maintaing the summary of regional emperical values.

The Way

The properties of main water ways and infrastructure of rural water systems are often determined by very general design methods. These methods are based on standards that use only little information of the actual water system. Most design methods applied in the Netherlands are based on land use and soil texture. Standards have been developed on the basis of generalized properties of water systems. Details of the actual layout of the water system and the way in which that system is controlled, are usually not incorporated. Present-day dynamic simulation programs and the computer power currently available enable more detailed modeling and incorporation of location-specific data into models. Such models can be used to design the water system and can include real data. A model-based design method is introduced, in which the actual situation of the water system is taken into consideration as well as the way in which the water system is controlled. Stochastics concerning the operation and availability of controlling infrastructure are included in the method. Models can be evaluated by including real data. In this way the actual safety of the water system, for example during floods, can be determined. Water-quantity design criteria can be incorporated as well as water-quality criteria. Application of the method makes it possible to design safe water systems in which excess capacities are avoided and in which all requirements of interest are met. The method, called the ‘dynamic design procedure’, can result in considerable savings for water authorities when new systems have to be designed or existing designs have to be reconsidered.
