Study On Foundation Treatment Technique In Mountainous Areas

With the rapidly increasing development of national economy, soil resource for construction is more and more scarce. In order to meet the need of produce and life, it is inevitable to construct buildings in mountain areas. The terrain is complex and the geologic structure is unstable in mountain areas. The ground is likely to appear bad geological phenomenon, for example, coast ground, uneven ground, limestone ground and so on. It is necessary to improve the ground in order to meet the need of the buildings. How to find secure, feasible and reasonable measures to improve the ground has very strong practical significance under the condition of geology, technology and fund.Firstly, this study summarizes the present domestic and foreign common methods to improve ground; introduces the theory, applicability and development of the technology to improve ground. Then, it analyzes the ground characteristic and introduces the common ground types and ground treatment to the bad ground in mountain areas. This study takes the example of the base science project for Beijing Forestry University to study. This project is located on the hillside. The ground of the project is typical montane ground and its geological condition is complicated. Retaining structures and drainage are adopted to stabilize the slope. The gravel paddings with different thickness are taken to improve the ground and make the ground sink in the same size. The well with crevice water was dredged to improve the ground and the effect is good.This study educes the satisfying foundation treatment solution taking into account of safety, feasibility and rationality, which is referenced to the treatment of the same type ground.
