摘要: 介绍了贵州位于浅埋基岩上某工程的岩基承载力取值,对比了强风化岩的岩基载荷试验和深层平板载荷试验,表明风化岩的变形性状和承载能力与基础形式有关。对于深基础,岩体埋置越深,变形模量越高,承载力也越高。工程实践中应利用桩基础和天然地基承载力性状的区别,合理设计以提高地基承载力。Abstract: The selection of bearing capacity values of a project in shallow rock foundation in Guizhou Province is introduced. The deep plate load tests and the rock foundation static load tests are comparatively analyzed. The results show that the deformation modulus of the strong weathered rock increases with the increase of the buried depth. Different bearing capacity behaviors of the pile foundation and shallow foundation should be considered in engineering practices to enhance the bearing capacity of foundations.
