确定岩体变形和强度参数最常用的方法有三种：原位试验法、经验关系法及数值分析法。
There are three kinds of methods to confirm the rock deformation and intensity parameters:in situ test, experiential relation method and numerical analysis method.
在卸荷带内进行35点原位变形试验，其加载路径和最大压力与拱坝作用于岩体的条件相似。
In-situ deformation tests are made at 35 points in the unloading zone with conditions of loading path and the maximum pressure similar to that of the arch dam acting on the rock mass.
