The rapid development of deep foundation pit engineering, has become an important part of the urbanization construction, which brings deep excavation support of geotechnical engineering problem research also became a major issue. This paper uses the international well-known geotechnical engineering numerical simulation software FLAC3D, through 3D finite difference numerical calculation and analysis, to better simulation calculation and analysis of deep foundation pit construction site condition, forecast after excavation of the deep foundation pit deformation displacement and dangerous position, analysis of deep foundation pit excavation process isolation pile - steel shotcrete combined support effect. Three dimensional numerical model analysis and calculation in deep foundation pit engineering design and construction scheme optimization with economy is convenient wait for a obvious advantages, can for deep foundation pit excavation of deep foundation pit support design and construction to provide effective basis.

Centrifuge Model Tests

The primary methods are antetype observation and model tests which to check the actual engineering status in geotechnical engineering field. The antetype observation is the best direct and convictive method, but approach miscellaneous and spend hugely. The general model tests can not fulfil the same stress between model and antetype. Geotechnical centrifuge model test can not only minish the measure of model and fulfil the comparability condition, but also can found all kinds of non-symmetrical models and simulation all kinds of complicated engineering. So the geotechnical centrifuge model test is applied widely in the geotechnical engineering. This paper used the RFPA-Centrifuge and recured to the principle of geotechnical centrifuge model test, evaluated the safety of model only by increase the physical strength. Though the numerical calculating in nonhomogeneous models with different scales showed that stress, displacement and failure mode were accord with conform ratio of centrifuge model tests. Showed the advantage that the results of RFPA can be validated each other with results of physical tests. For some specifical complicated items in geotechnical engineering, make a good test model is not only very hard and have to spend much time, but also need expensive test equipment and much money for test materials. It is very good if we can use a method to conquer these shortages. So it is advisable that using the mechod which geotechnical centrifuge tests combine RFPA-Centrifuge numerical simulation analysis method.

Landslide is a kind of global geological disasters, causing casualties and huge economic losses to many countries and regions. Analysis on the study of slope stability is very important geotechnical engineering in the field of content. Taking Dalian Xinghai long garden landslide as an example, based on the detailed investigation of geological disasters in Dalian Xinghai area, using the Soilworks software to analyse evaluation of landslide treatment effect.

Soil Behaviour

Non-coaxiality has been recognized as an important feature of grain materials in geotechnical engineering. Without considering the non-coaxiality in structure design will lead to an unsafe result. Studies on the non-coaxial soil behaviour have been carried out both using numerical simulation and experimental testing by several researchers. To discuss the non-coaxiality of sand, it is essential to carry out tests under various stress paths. HCA is a valuable device to investigate the soil behaviour under various stress paths. In this paper, a review of the experimental work on non-coaxial soil behaviour especially using HCA is presented to help the understanding of both non-coaxiality and the use of HCA.

In order to solve the problem of bumping at bridge head of bridges in our country and reduce the void volume of bridge end transition slab, the method of embedding rigid permeable plates is proposed in this paper. Combined with different engineering situations and using geotechnical engineering stress and strain professional analysis software SIGMA/W to model, the performance and engineering applicability of rigid permeable plates are numerically simulated. The results show that the bearing capacity of rigid permeable plate meets the engineering load requirements and is in line with the engineering applicability; Embedding rigid permeable plate can effectively reduce the void volume of bridge end transition slab, especially when the compactness of abutment back is lower, the effect of rigid permeable plate on reducing the void volume of bridge end transition slab is more obvious. The proposed method of embedded rigid permeable plate provides valuable theoretical and scientific basis for solving the problem of bridge head jumping.
