Pit Supporting Engineering is an important part of the geotechnical and it’s an important technical aspects to ensure the stability Pit. In the rapid development of the city, most of the pit should be constrained by the surrounding environment, which put forward higher requirements to support technology. We must ensure not only the security and stability of the supporting structure itself, but also ensure that the surrounding is not affected. For the support characteristics of pile anchor supporting unique and stress performance, it has been widely used in the construction process at this stage.Meanwhile, in order to ensure the security and stability of the excavation support system, engineering testing has become a pit integral part of the support. This paper takes a engineering example of Handan as the research object and simulates the pile anchor supporting the latest research situation, the design theory, the stability and the research of three dimensional numerical engineering.By consulting a large number of home and abroad journals, documents, this paper firstly studys that how to use the pile anchor support in the design of foundation pit research status to understand the pile anchor supporting the forefront of research. This paper Mainly summarise as:earth pressure the research situation, the pile anchor supporting theory research in present situation and the latest design method, which provides a basis for further research of pile anchor support.Secondly, This paper introduces the earth pressure calculation principle, pile anchor support overall stability, resistance to overthrow and resisting uplift stability checking computations.what’s more, it use deep foundation pit design software for6.012d plane check to ensure the stability of foundation pit.This paper focuses on simulating the engineering by using three-dimensional numerical software FLAC3D. It analyzes the the settlement of soil around the foundation pit and foundation pit lateral horizontal displacement, uplift and supporting pile bending moment to draw the general change rule. |
