摘要
福建沿海地区出露了大面积的燕山期花岗岩,在长期的风化作用下,形成了花岗岩风化壳,它们是该区建筑物的主要持力层。探讨该区花岗岩及其风化岩石的物理力学性质的特征,对于工程建设具有现实意义。本文在总结分析试验资料的基础上,给出了该区花岗岩物理力学指标的统计值、变化范围及其相关方程。在此基础上,讨论了风化因素对花岗岩力学强度的影响。
In the coast of Fujian province there are a lot of Yanshanian granite masses which formed weathering crust by long term weathering. It is the main loading layer of the buildings in this area. It is practically significant for engineering construction to study the characteristics of physicomechanical property of the granites and their weathered products. Statistical values, range of variation and correlation equation of physicomechanical indexes of the granites are obtained on basis of summarizing the test data. Then the effect of weathering on mechanical strength of the granites is discussed.
