钻孔压水试验测试仪及其在古贤水利枢纽工程中的试验应用

Experimental Application of Borehole Water Pressure Test Instrument in Guxian Hydro-junction Project

摘要:

工程地质勘察中进行干深孔的常规性压水试验是长期困扰水利水电钻孔压水试验的技术难题，为解决该问题，自行研制了钻孔压水试验测试仪，并在古贤水利枢纽工程中进行了试验应用，取得了很好的效果。结合工程实践，综合分析了钻孔压水试验测试仪在古贤水利枢纽中的试验应用情况。

Abstract:

Conventional water pressure test in dry deep hole of engineering geological investigation has been a technical problem in water pressure test for water conservancy and hydropower borehole. To solve the problem, borehole water pressure test instrument was developed and experimentally applied in Guxian hydro-junction project with good results. Based on the engineering practice, the paper made the comprehensive analysis on the application situation.
