摘要
以水布垭面板堆石坝施工中的过渡料(ⅢA)和主堆石料(ⅢB)为主要检测对象,分别进行了面波波速和试坑置换法干密度的对比检测试验。检测成果的回归分析表明:同一种坝料的面波波速与干密度之间具有良好的线性相关性,可建立相关方程。根据相关方程由实测波速推测压实干密度值,相对试坑置换法的实测值,误差在±1%范围内。本项试验为推广应用稳态面波法检测干密度值提供了理论依据和工程实践经验。
Surface wave velocity detecting tests and dry density detecting tests by pit replacement method were conducted respectively for the transient material (ⅢA) and main rock-fill material (ⅢB) used in the construction of concrete-faced rock-fill dam of Shuibuya Project. The results from regression analysis show: there exists good linear correlation between surface wave velocity and dry density detected at same place of compacted rock-fill layer, so a correlation equation may be established. The relative difference between values of dry density measured by wave velocity method and pir replacement method is in the range of ±1%. The study provides basic detection theory and practicel engineering experiences for popalarizing surface wave velocity method to detect dry density of compacted rock-fill layer in practice.
