There can be many reasons for engineers to place the footings near a slope such as leakage of suitable sites or architectural considerations. One of the approaches to increase the amount of bearing capacity, especially in soft soils, is adding stone columns to the soil. In this research, the behavior of a strip footing placed near a stone column reinforced clayey slope was investigated. For thi...

Abstract On road/ bridge construction, foundation stability analysis is carried out by reviewing the bearing capacity. At planning stage, this aspect can be calculated based on empirical and numerical methods using In-situ Dynamic Penetration Test data. Meanwhile, at implementation capacity results are checked Pile Driving Analyzer (PDA). Hereinafter, result in field compared with stage whether...

The accumulation slope is widely distributed in the mountainous area of China; this paper takes Chengdu–Lanzhou Railway as engineering background and analyzes stability mechanical properties anti-slip pile under symmetrical train loads. First, finite element software Midas GTS NX was used to analyze effect after support at different spacings, row distances, positions. Then, analysis results pil...

An effective way to strengthen shallow foundations is contour reinforcement - the execution of vertical elements in soil base along edges foundation. The introduction that perform function a "compression wall" leads noticeable decrease deformations and an increase bearing capacity at reinforced foundations. As reinforcing elements, various structures materials with strength properties exceed co...

With help an underground dam, conditions flow are created, The studies were performed using midas GTS NX software package. Mathematical modeling was wxMaxima Results. A set technical devices combine...

The theoretical calculation of a counterweight double-row pile supporting structure is deduced and studied in this paper. derived method applied to Midas GTS NX simulation calculation. A case study deep foundation pit project Shenzhen City used verify analyze the results field monitoring results. On basis, influence law deformation parameters such as row distance, diameter back-row piles load t...

Abstract It is inevitable for the construction of subways to pass under existing structures in city; this will cause settlement and affect their safety. The soil a complex mixture, hence it difficult determine damage caused by using tunnel boring machine (TBM) method stress balance surrounding soil. Normally, uplift surface are during tunneling . Therefore, large-scale 3D simulations needed stu...

Deep foundation pit construction adjacent to a subway station in soft soil area was numerically simulated with Midas GTS NX calculation software. The influence of the deep on deformation and stress structure studied, retaining analyzed. results show that during excavation process, slab rose as whole greatly affected by common ground connecting wall, most unfavorable position changing changed. p...
