摘要
在假定破坏的有效机构满足弹性—理想塑性理论及库仑屈服准则的前提下 ,利用极限分析法的上限定理对土体中泥浆护壁钻孔的极限孔深问题进行计算研究 ,计算中考虑了护壁泥浆、孔壁土体的性质及孔径等对孔深的影响。
Supposing that broken effective apparatus satifies elastic-plastic theory & Kuron submission principle,it calculates & researches limit hole depth of mortar hole in soil by maximum theorem of limit-analyzing method in which influence to hole depth is considered.
