摘要
针对广东某工程项目强风化的岩体特性,探讨利用钻孔膨胀计PROBEX来进行循环径向加压试验以获得强风化岩层力学参数。试验结果表明:循环径向加压试验所采集的数据采用一些列方法处理后能得到岩体旁压变形模量以及旁压弹性模量,可反映岩体坚硬程度与地基承载力的大小,钻孔径向加压试验可用于测定强风化岩层力学参数。
Aiming at the characteristics of the strongly weathered rock mass of an engineering project in Guangdong,the use of the borehole dilatometer PROBEX to carry out a cyclic radial compression test to obtain the mechanical parameters of the strongly weathered rock formation was discussed.The test results showed that the data collected in the cyclic radial compression test can be processed by a series of methods to obtain the side pressure deformation modulus and the side pressure elastic modulus of the rock mass,which can reflect the hardness of the rock mass and the bearing capacity of the foundation.
