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.

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。

Corrosion pitting also can lead to fatigue crack initiation depending on the component, the location of pitting, and cyclic loading conditions.

腐蚀斑点还会因不同的部件、斑点的位置和循环载荷状况，导致一些不同的疲劳裂纹。

The degree of cracking tolerated before fracture varies by component, crack location, and component loading conditions.

断裂之前承受裂纹的能力依部件、裂纹位置和部件承载情况的不同而论。
