摘要
结合云南省罗平县大麦田水库岩溶库区防渗处理,对拟选用的土工膜材料进行了现场铺设损伤、土工膜搭接工艺等系列室内模拟试验研究,重点通过大型渗透试验及条带拉伸试验,检验了所选膜料规格的合理性及施工工艺的可行性,解决了现场施工中一些关键技术问题,并建议了合适的过渡层材料。
The paper has carried on the simulated in-situ lapping and laying damage tests and study of the proposed geomembrane material in the lab, giving first priority to verification of rationality of the specification of the proposed geomemvrane as well as of feasibility of the construction technology by conducting large-scale impermeability tests and strip elongation tests. The paper has solved some key technical problems in practical construction of the projects. Moreover, The paper has proposed suitable transition layer materials.
