| 摘 要： | 采用水压致裂法和钻孔孔壁应变测量法两种测量方法对广西岩滩电站二期工程地下厂房区进行了地应力量测。通过对实测资料进行比较和分析认为：两种方法测量的成果一致性较好；岩滩电站二期工程地下厂房区处于一般应力水平；受复杂地质构造影响，地下厂房区存在构造应力痕迹；地下厂房轴线与最大主应力σH方向为小角度相交，地应力场对厂房洞室稳定有利；地应力场对地下厂房稳定性的影响有限。

| Abstract: | With two methods of hydro-fracture and borehole strain over-coring,geo-stresses were measured for the underground plant area of Yantan Hydropower Station,Guangxi.By the comparison and analysis for the measured information,the results reveal that there is better consistency for the measure achievement of two methods;Yantan Hydraulic Station's underground plant area is in exist middle stress level;there exists tectonic stress characteristic obviously in the underground plant area for the influence of the geo-... |
