大跨度洞室的最小矢跨比是大跨度洞室尺寸设计的重要参考依据,基于能够考虑岩体软化、剪胀、体胀、密度变化等开挖响应特征的Cavehoek本构模型和能够反映不同岩体质量、岩石单轴抗压强度条件下的极限应变标准,对不同地质强度指标GSI、埋深、侧压力系数、结构面等条件下的60 m大跨度洞室的最小矢跨比进行了研究。结果表明,GSI、侧压力系数、埋深3个因素中,GSI对大跨度洞室的最小矢跨比影响最大,侧压力系数和埋深次之;岩体质量越好,最小矢跨比越小,最小矢跨比与侧压力系数和埋深之间并非线性关系。结构面和岩石单轴抗压强度对大跨度洞室最小矢跨比有较大的影响,尤其是缓倾结构面非常不利于大跨度洞室成拱。

初始地应力场特征是地下工程稳定分析中最重要的条件,为了评价开挖后地下洞室的围岩稳定及支护设计的长期安全,需要对围岩的初始地应力场进行反演。在对雅砻江卡拉水电站工程区地应力实测值进行分析的基础上,根据世界地应力图和GPS地表监测数据所确定的区域地应力特征,选取地下厂房区域测试可靠、具有代表性、离厂房区域较近的实测点作为初始地应力数值反演分析的回归对象,结合反演分析原理,获得整个地下厂房区域的地应力场分布特征。通过对比数值计算值和实测成果可知:测点地应力的大小和方向拟合程度较好,分布规律大致相同,表明采用数值反演分析方法的合理性。分析成果为地下厂房洞室群的布置、开挖支护设计等提供了依据。

锦屏二级水电站大理岩在高的地应力条件作用下表现出破裂随时间扩展的现象,给引水隧洞的运行期安全产生重大的影响。现场开挖后出现的滞后破裂现象、锚杆应力计和声波测试都反映出大理岩破裂随时间发展的特征。首先采用室内试验和数值分析,证明破裂是大理岩开挖后的主要响应方式,表明锚杆应力计和声波测试在现场测试中具有更好的适用性,而多点位移计敏感性较差。利用GSI随时间指数递减代表大理岩强度随时间递减,进而表征隧洞开挖损伤区随时间的增加而增加,在此基础上,建立应力腐蚀模型SC。将现场已获得的监测数据作为SC模型中相关参数的校核依据,对大理岩的长期力学响应、锚杆受力状态和衬砌结构安全性进行详细分析,采用SC模型得出的特征与现场实际开挖响应具有很好的一致性。
