一、研究意义风化壳垂直分带的研究是岩体工程地质性质研究的一个不可忽视的方面。由于岩石的风化,导致岩体物理力学性质的恶化,从而影响工程建筑的稳定性。重要的工程,一般当风化壳厚度不大时,可将全部风化岩石清除,使建筑物砌置在新鲜基岩上;但是当风化壳厚度较大时,全部挖除风化岩石既不经济,技术上也很困难,此时,岩石风化程度及其分带的研究便是建筑物选址、设计、施工及地基处理时,进行各种方案比较的重要依据。
I. Research Significance The research on the vertical zoning of weathered crust is a non-negligible aspect of the research on the engineering geological properties of rock mass. Due to the weathering of the rock, the physical and mechanical properties of the rock mass deteriorated, which affected the stability of the engineering building. In important projects, when the thickness of weathering shells is not large, all weathered rocks can be removed and the building can be placed on fresh bedrock. However, when weathering shells are thick, it is neither economical nor technical to dig out weathered rocks. It is also very difficult. At this time, the study of rock weathering degree and its zoning is an important basis for comparison of various plans when building site selection, design, construction and foundation treatment.
