摘要
以福建华东船厂修造船项目帷幕灌浆检测试验为工程依托,对比分析钻孔注水原位试验、室内土工试验、以及经验公式取得的渗透系数,通过研究粗细粒土的含量对渗透系数的影响,提出适用于初期判断渗透系数的快速经验公式,能较好地应用于福建地区花岗岩风化体,并得到相关工程的验证。
Taking a curtain grouting testing of FuJian HuaDong Shipyard Company ship repair projects as an example,it analyzed permeability coefficient of pouring water into borehole in- situ test laboratory soil test and empirical formula. By studying the content of the effect of coarse- grained soil and fine-grained soil,it came up with the quick empirical formula for which is applied to weathered granite in FuJian and validated by related engineering projects.
