一、前言自解放以来,我省兴修了很多的中小型土坝工程,为了对这些土坝工程的质量进行检验,曾在重点土坝上钻探取样试验,并埋设了简易的观测设备,如沉降标、位移标、测压管、量水圳等,由于基础处理不善,坝体夯压不实,坝段接头不良,填土质量不佳,运行不当等原因,当库内蓄水后产生的问题较多,我省常采用粘土心墙砂壤土坝壳;粘土心墙、砂壤土过渡段、砂砾坝壳的坝型。在这类坝型中,尤以裂缝的迹象较普遍,同时也有集中渗漏等 I. Preface Since the liberation, a lot of small and medium-sized earth dam projects have been built in our province. In order to test the quality of these earth dam projects, we have conducted drilling sampling tests on key earth dams and laid out simple observation equipment such as settlement Standard, displacement standard, piezometric tube, the amount of water and so on, due to poor foundation treatment, dam body ramming, dam joint poor, poor filling quality, improper operation and other reasons, More problems, our province often use clay heart wall sand loam dam shell; clay heart wall, sandy loam transitional section, gravel dam shell dam. In this type of dam, especially the signs of cracks more common, but also focus on leakage and so on
