在水利水电建设中,软弱夹层往往是工程稳定的控制因素,因此,对软弱夹层的危害应结合工程实际来评价。其中,各种参数测试与分析的准确与否,将会对工程建设的经济费用和生产的安全性产生显著的影响,甚至带来严重的后果。为了使测试准确,必需制备原状试样。传统的做法是取扰动夹泥进行土工试验,或者采用扰动岩块复原后制成试样进行室内中型剪试验。这些方
In the construction of water conservancy and hydropower, the weak sandwich is often the controlling factor of engineering stability. Therefore, the harm to the weak sandwich should be evaluated in conjunction with the actual project. Among them, the accuracy of various parameter tests and analysis will have a significant impact on the economic cost of construction and the safety of production, even with serious consequences. In order to make the test accurate, it is necessary to prepare the original sample. The traditional method is to take the mud from the disturbed soil to perform the soil test, or use the disturbed rock mass to recover and make the sample for the indoor medium shear test.
