摘要
针对河谷地应力实测点之间测值比较分散、协调性较差这一问题，提出了以河谷地应力场形成过程为基本依据、用二次正交试验与三维弹塑性有限元相结合的数值检验方法，它可以评价地应力测值的代表性及彼此之间的协调性，并可反映出全场地应力状态。
Because of the disparity and poor identity of in situ stress measurements among different points at valley, a numerical check technique is presented, which is based on the form process of in situ stress field of valley and combined orthogonal experiment theory with 3 D elasto plastic FEM. It can be applied to check the representativeness of in situ stress measurements and their identity, and also simulate the in situ stress field of valley.
