【摘要】 小南海水库坝体是地震堆积体,渗漏严重,采用帷幕灌浆方案进行防渗整治。天然地震崩塌堆积体的帷幕灌浆质量检查方法没有规律可循,本文主要介绍了渗流测压管的施工工艺,并对帷幕灌浆前后天然坝体渗透压力变化情况进行观察。更多还原

【Abstract】 The body of Xiaonanhai Reservoir dam was formed by earthquake accumulation body and with serious seepage,which was treated in the way of curtain grouting.But there is no law to be followed to check the curtain grouting quality of natural earthquake accumulation body.The construction technology of piezometer tube and some inspection on the pressure changes before and after the grouting were introduced.更多还原
