On the base of least squares,using measured data and some optimization methods,both BDM and SFM can get the simulation of stress field and directly provide initial stress state for subsequent stability analysis of slope.

• 这两种方法是利用现有的实测数据，基于最小二乘法制定目标函数，采用一定的优化算法，结合有限元分析程序，得到岩体初始地应力场，并直接为后续的边坡稳定性分析提供初始应力状态。
