| 摘 要： | 结合水电站工程实例，在现场调查和工程地质勘察结果的基础上，详细分析某隧道的裂缝形成原因，主要是1885m高程以上边坡失稳的影响、地应力的作用、1885m以下边坡的不当开挖、动静荷载和施工渗水等几种因素，排除了混凝土干缩和温度应力两个影响因素。

| Abstract: | This paper combined with one of the southwest China hydropower Projects,and on the basis of on-site investigations and the results of geological prospecting works,make a detailed analysis for the reasons of the tunnel cracks.And the reasons including the following:the first is the impact of the slope instability above 1885 elevation;secondly,the role of the rock stress;the third is the improper excavation of the slope below the 1885 elevation;the forth reason is the dynamic and the static loads the;last one is the water seepage.Ruled out the factors of the concrete shrinkage and thermal stress. |
