田村水库碾压式风化料心墙堆石坝及膜料防渗技术研究

Researches of the seepage prevention technique with film material and the rolled corewall type rockfill dam with weathering stones of the Tiancun reservoir

田村水库大坝是目前国内新建土石坝采用土工膜同风化料心墙组合防渗、土工织物反滤技术的最高土石坝之一，且同时采用风化料心墙、土工膜防渗、土工织物反滤综合筑坝技术在国内尚未见报道。为此，对其风化料、堆石体、土工膜防渗、土工织物反滤筑坝技术进行一系列的试验论证研究，成果应用后，取得了较好的经济效益。

The Tiancun reservoir dam is one of those new built highest dams using weathering stones corewall and earthworks filmfabric filter composition seepage prevention technique in our country now.lt hasn't been reported in our country that,in same a dam,used the above items of building dam technique in the meantime. The researchers made a series of test,demonstration and researches to those composition seepage prevention building dam technique.The result brought better economic and social benefit.
