摘要

Hardfill dam is a new type of dam, which is developed recently. The aim of the paper is to analyze what geologic condition is suited to construct the dam by considering the characteristic of the Hardfill dam itself and to study for the given geologic condition how to choose the reasonable impervious and drainage system to control the dam body and foundation's seepage to make sure the safety of the project. After analyzing many familiar dam foundations geologic condition, two types of typical Hardfill dam foundation are concluded. The dam foundation seepage field law is analyzed by dam foundation seepage discharge, uplift pressure and seepage gradient of some typical positions after setting reasonable impervious and drainage measures on the two dam foundations. The calculation results show the adaptability of Hardfill dam foundation is comparatively nice, and the dam foundation safety can be ensured if appropriate impervious and drainage measures are adopted.
