土钉倾角对基坑工程的影响研究

Research on the affection of soil-nail obliquity to foundation ditch projects

结合工程实例,对土钉支护参数的设计计算进行了介绍,并计算了不同倾角情况下基坑最大水平位移、土钉最大拉力和工程中所需土钉的数量,分析了不同倾角对基坑稳定性及造价的影响,得出的一些结论对基坑土钉支护法的研究有一定的实际意义。

Combined with the projects examples, it introduces the design and calculation to soil-nail support parameter, calculates the maximum horizontal displacement of foundation ditch, the maximum pull of soil nail, and the quantity of soil nail that needs in projects of different obliquity, analyses the affection of different obliquity to the stability of foundation ditch and the costs, and deduces some conclusion that has certain practical meaning to the research of soil-nail support.
