该工程由于坝体填土的干容重偏低,故十分担心其安全问题。通过原体观测资料的整理分析和室内电模拟试验验证,提出下列几点意见:①当库水位达某高程时,1~#测压管水位变化有异常现象,经挖坑检查证实在该高程位置上下土层分界明显,上部填土均匀性差,密度低且含水量大。②根据Ⅱ—Ⅱ观测断面分析,在高库水位情况下,测压管水位与库水位呈同步变化,2~#和7~#两管的实测水位要较试验值高6～10和5～12米左右。对上述问题均应引起足够重视。
Due to the dry weight of dam filling, the project is very worried about its safety. Through the analysis of the original observation data and the indoor electrical simulation test, the following opinions are put forward: ①When the reservoir water level reaches an elevation, the water level changes of 1 ~ # piezometer have abnormal phenomenon. The upper and lower soil layers are obviously demarcated, the upper soil homogeneity is poor, the density is low and the water content is large. ② According to Ⅱ-Ⅱ observation section analysis, under the condition of high reservoir water level, the piezometric water level changes synchronously with the reservoir water level. The measured water levels of 2 ~ # and 7 ~ # pipes should be 6-10 and 5 ~ About 12 meters. All the above issues should be given enough attention.
