abstract: This study evaluates load variations in instrumented prestressed ground anchors installed in a bored pile retaining wall system in sandy soil. Data were collected from instrumentation assembled in the bonded length of three anchors, which were monitored during pullout tests and during different construction phases of the retaining wall system. Instrumentation consisted of electrical resistance strain gauges positioned in five different sections along the bonded length. Skin friction distributions were obtained from the field load measurements. Results showed that the skin friction followed a non-uniform distribution along the anchor bonded length. The mobilized skin friction concentrated more intensely on the bonded length half closest to the unbonded length, while the other half of the bonded length developed very small skin friction. The contribution of the unbonded length skin friction to the overall anchor capacity was significant and this should be accounted for in the interpretation of routine anchor testing results. Displacements applied to the anchor head were sufficient to mobilize the ultimate skin friction on the unbonded length, but not on the bonded length. Performance of loading-unloading stages on the ground anchor intensified the transfer of load from the unbonded length to the bonded length. Long-term monitoring of the anchor after lock-off revealed that the load at the anchor bonded length followed a tendency to reduce with time and was not significantly influenced by the retaining wall construction phases.

Using self―made model device, researchers studied the characteristics of foundation settlement of sandy soil and pile foundation load―bearing in sandy soil. Through weight loading, researchers analyzed the phenomenon of foundation settlement. Then, researchers embedded friction piles in sand, so as to analyzed pile foundation bearing capacity. The methods and results of the research can provide guidance for teaching of Soil mechanics and foundation engineering.

Bored Pile

A viaduct of the Qinglai expressway fourth contract was artificial excavated piles. The construction technical work was regarded as an example. The technical comparison were done between the artificial excavated pile and the bored pile on the pile foundation bearing capacity and the retaining wall effect . The artificial excavated pile replacing the bored pile was feasible, and the construction technology and the key problems of the artificial excavated piles were confirmed. The references were provided to the similar projects.

Der globale Bedarf an faserverstärkten Kunststoffen (CFK) wächst aufgrund seiner herausragenden Eigenschaften gegenüber konventionellen Leichtbauwerkstoffen in der Automobil- sowie Luft- und Raumfahrtbranche stetig an. Für deren Endbearbeitung kommen überwiegend Fräsprozesse zum Einsatz, welche Verschnitt in Form von Faserbündeln im Mikrobereich erzeugen. Ein vielversprechender Ansatz die Ressourceneffizienz zu erhöhen, ist der Einsatz der Fräspartikel als Füllmaterial in Thermoplasten.   Due to the outstanding material properties of fiber reinforced plastics towards conventional lightweight materials, its global demand in the automotive and the aeronautical sector is growing steadily. For the machining of final contours, milling processes are mainly utilized, which create chips in form of fiber bundles in the micro range. A promising approach to increase the resource efficiency is the use of the milling particles as filler material in thermoplastic materials.

Currently, bored pile been widely applied in the current road and bridge construction, But its construction technology in complex geological case is still not perfect. In view of this, this paper carried out a high-speed Lakes viaduct extraordinary pile foundation construction project. For the analysis of the technical difficulties in the construction process, explore get the corresponding key construction technology, and it relates to the accident and its approach are summarized, study drew long pile construction technology Lakes geological conditions under soft silt and clay, solve the long holes bored pile into the lake silt soft clay under geological conditions, verticality control and other technical problems, can provide reference for similar projects.
