岩体赋存深度与力学参数相关性研究

Study on Correlations Between the Occurrence Depth of Rocks and Mechanical Parameters

对湘东地区某变电站岩石试样单轴抗压强度试验值进行了统计分析,分析研究表明,在岩体风化因素类似的一定范围内,单轴抗压强度基本与赋存深度成正相关。可利用岩体至基覆界面深度作为赋存深度,采用线性趋势线求得岩石力学参数,使基础设计安全且经济。

The uniaxial compressive strength of rock samples from a substation in eastern Hunan province is statistically analyzed in this study. It is shown that within a certain range of similar weathering factors, the uniaxial compressive strength is positively correlated with the occurrence depth. With the depth from the rock mass to the bedrock cover interface as the occurrence depth, the rock mechanics parameters can be obtained by using the linear trend method, which makes the foundation safe and economical.
