Abstract: Aiming at the abnormal increase of measured seepage pressure in clay sloping core dam, the reason for abnormal increase is comprehensively analyzed combining with the instrument embedment. In order to know the effect of abnormal increase on the seepage stability and clay sloping core and provide reference for engineering operation, the FEM to calculate the seepage field before and after the abnormal increase is carried out.

Key words: clay, sloping core, osmometer, seepage, stable

摘要： 针对某粘土斜心墙坝内渗压计测值异常增大的现象，结合仪器埋设情况，综合分析测值异常增大原因。利用有限元分别计算测值异常增大前后的渗流场，并进行对比分析，以掌握异常增大对粘土斜心墙及渗流稳定的影响，为工程后期运行提供参考性意见。
