摘　　要：其宗水电站深厚覆盖层，其成因复杂，包括冲积、洪积、冰积、泥石流堆积和崩积等多种成因。由于覆盖层厚度大，组成物质均一性差，因此在钻孔内开展原位旁压测试试验，为分析、研究在深厚覆盖层上建坝的可行性、适宜性提供可靠的试验成果具有重要意义。本文对其宗水电站坝址河床及阶地深厚覆盖层的孔内旁压试验实践及试验成果分析进行介绍。The causes of formation of the deep coverage layer in Qizong Hydropower Station are complicated, including alleviation,pluvial sediment, ice accretion, debris flow sediment, and the colluvial, etc. Because the coverage layer is thick, with bad homogeneity of component substances, the in-situ lateral pressure test is carried out in the borehole, having important significance in providing reliable test results for analyzing and researching the feasibility and applicability of on building dam on the deep coverage layer. The paper introduces the hole lateral pressure test practice and test results analysis on dam site riverbed and terrace deep coverage layer in Qizong Hydropower Station.
