随着我国工程建设规模的不断扩大,越来越多的大中型工程项目建设在软岩场地上,能否准确获取软岩岩体变形参数,关系到建构筑物地基安全及经济。该文以刚形承压板法在软岩场地进行岩体变形试验,按照《工程岩体试验方法标准》(GB/T 50266-2013),针对软岩地基采取逐级一次循环法进行试验,分析了同种岩性不同完整程度、同种岩性不同深度的软岩岩体在1.2倍设计载荷作用下的变形特性。
With the continuous expansion of construction scale in our country, more and more large and medium-sized construction projects are being built on soft rock sites. Whether the deformation parameters of soft rock and rock mass can be accurately obtained is related to the safety and economy of the foundations. In this paper, the deformation test of rock mass is carried out in the soft rock site by the rigid bearing plate method. According to the standard of test method for engineering rock mass (GB / T 50266-2013) The deformation characteristics of soft rock mass with different intactness and different depth of the same kind of lithology under 1.2 times of design load are analyzed.
