| 摘 要： | 使用Matlab编制了土钉墙支护和单支点桩板支护结构的计算程序,并在土钉墙支护结构的程序中将条分法进一步精确,使用完全积分的方法准确地搜索出了最不利滑移面的位置,根据该滑移面的位置及形状大小确定每根土钉的计算长度,使得土钉长度的计算更具合理性,然后通过不同基坑开挖深度时的计算对2种支护结构形式的经济性作了对比分析,为今后的实际工程设计提供参考.

| Abstract: | By using Matlab, a caiculation program of the two supporting structures, soil nailing walls and the pile-slab retaining structures of one-supporting anchor was developed. In the program of soil nailing walls, the soil slice method was substituted by the integral method, and then the critical slip surface was searched out correctly. The length of each soil nailing was determined according to the critical slip surface. The length by this method is more reasonable than that the national code method. Finally, the engineering costs of the two supporting structures were by compared on the basis of a series of depth of foundation excavation, and some useful conclusions were drawn for practical engineering designs. |
