【摘要】 利用弹性力学、土力学和材料力学等理论,对在软弱土覆盖层厚的地基上设计和建造桥梁钻孔桩基础时,对成孔过程中的护壁、塌孔等问题进行受力分析,以便于指导钻孔桩的设计、施工和预防塌孔事故.更多还原

【Abstract】 Using theories such as elastic mechanics,soil mechanics and material mechanics,a mechanical analysis is given for the dado and breakdown while bored piles are formed in the designing and building structural foundations on the grounds covered with the thick layers of soft soils.The results can guide the design,construction of bored piles and prevent hole collapse accident.更多还原
