摘要
针对圆弧条分法在复合地基的稳定性计算中计算繁琐且不确定性过多的问题,利用积分公式对圆弧法进行改进,从而推导出求解稳定系数的积分公式。结合实例对圆弧法和改进方法进行比较,结果证明,改进方法接近实际,且减少了计算的次数,又使得搜索的过程有系统性,易被工程人员掌握。
According to the shortages of the circular-arc method＇s complexity and too much uncertainty in the calculation of the stability of composite foundation, the integral formula is used to improve the circular-arc method, so as to derive the integral formula for solving the stability factors. Then the improved method mentioned here is compared with the cir- cular-arc method by examples. The results show that this improved method is closer to the reality, not only reducing the number of the calculation, but also making the search process in systematization. What is more, it is easy for engineers to know well.
