球状风化孤石群内端承桩复合成孔施工技术

Composite Construction Technology of Boring for End-bearing Pile in Spherical Weathered Boulders

把典型的崩岗剖面从上到下划分为：红土层、砂土层、碎屑层和裂隙风化层（亦称球状风化层）4个层次；

There are 4 layers in typical profile of slope disintegration : the red soil layer 、 the sandy soil layer 、 the detritus layer and the crack weathered layer ( also claimed the globular weathered layer );

介绍地层软硬不均、断裂破碎、硬岩、球状风化岩、水底浅覆土层等复杂地质条件对盾构施工的影响以及应采取的相应技术措施。

In this article , authors introduce influences of complex geologic conditions such as un-uniform hardness strata , rupture and breaking , hard rock , spherical decayed rock , underwater shallow-covered soil and so forth on shield construction , and state relevant technical measures should be adopted in construction .
