在地下工程防渗、堤防、水库等工程地质勘察中,测试岩土层的渗透系数对评价岩层与基岩的渗漏及稳定性有着十分重要的意义.因此,在工程地质勘察中需运用一定的方法来获取渗透系数(K),对岩土体进行渗透性及渗透稳定性分析评价.不同的试验方式会获取不同的试验结果.而试验结果的合理准确与否将直接关系到工程的稳定运行,选择合适的测试方法显得尤为重要.本文通过对注水、压水实验在实际工程中的运用进行对比分析,得出不同试验方法的工程实用性.

In the geological survey of underground seepage engineering, embankment, reservoirs, etc., the test of permeability coefficient has a very important significance for the evaluation of leakage and stability of rock layers and bedrock rock. Therefore, it is necessary to use certain methods to obtain the permeability coefficient (K) in the engineering geological survey and conduct permeability and seepage stability analysis and evaluation of rock and soil. Different test approaches will get different results. And whether the test results are reasonable and accurate or not will be directly related to the stable operation of the project, so it is very important to choose the appropriate test methods. In this paper, through the comparison and analysis of the water injection test and water pressure test in actual engineering, the practicability of different experimental methods is obtained.
