| 摘 要： | 现行《岩土工程勘察规范》(GB50021-2001)及《建筑地基基础设计规范》(GB50007-2002)规定,确定岩石地基承载力特征值常用方法有取岩样作室内试验和现场原位载荷试验等。软质岩的岩石试样作室内试验时,因环境条件与实地有明显的差异,试验结果多不理想,现场静载试验在实际环境条件下进行,能更好地挖掘软质岩石地基承载力特征值的潜力,减少基础工程造价。

| Abstract: | According to the regulations currently in effect on Surveying Standard of Rock and Soil Engineering(GB50021-2001) and Basic Design Code for Groundwork of Building(GB50007-2002),the common methods that define characteristic constants of bearing capacity of rock groundwork involve in-house test by sampling rocks and load test at original position on site,etc.When testing the samples of soft rock indoor,the results are often not ideal due to terms at surroundings different from at site,the statistic load experiment conducted under actual condition may develop the potential increasingly on characteristic constants of bearing capacity of rock groundwork and reduce the cost of foundation work financially |

| Keywords: | soft rock rock sample test statistic load test characteristic values of bearing capacity |
