摘　　要：碾压混凝土坝层间结合质量是碾压混凝土坝筑坝的关键薄弱点,关系到坝体稳定。文章以贵州善泥坡水电站碾压混凝土坝为例,为了解碾压混凝土层间结合情况及坝体上游坝面的防渗情况,通过选取在典型断面布设渗压计,对碾压混凝土层间结合情况进行了监测和分析,同时采用渗透压力强度系数的计算结果与监测情况进行对比分析,并结合现场实际检查情况,对碾压混凝土层间结合质量进行验证,为今后碾压混凝土坝层间质量控制提供借鉴。The interlayer combining quality of roller compacted concrete dam is the key weakness of roller compacted concrete dam construction which is related to dam stability.Taking the roller compacted concrete dam of Shannipo Hydropower Station in Guizhou as an example in order to understand the interlayer combining of roller compacted concrete and the seepage prevention of upstream dam surface the interlayer combining of roller compacted concrete is monitored and analyzed by selecting the osmometer arranged in the typical section.At the same time the calculation results of osmotic pressure intensity coefficient are compared with the monitoring situation and the quality of roller compacted concrete interlayer combining is verified according to the actual site inspection conditions which provides a reference for the future interlayer quality control of roller compacted concrete dam.
