新河口泵站地基抗渗加固中土工合成材料的设计

安徽省长江南堤新河口泵站前池地基发生多次渗流破坏,经在前池内设定长排渗降压沟,沟内铺设土工布,设置排水砂井、井内设复合土工布袋装砂砾石,达到了排渗降压、地基抗渗安全的目的。该文介绍减压沟内土工布及砂井内复合土工布袋的设计。

Design of Geotechnical Composite Material in Subgrade xxx Reinforcement of Xinhekou Pumping Station

The seepage breakage happens for many times in the subgrade of the front tank in Anhui Province Changjiang River South Embankment Xinhekou Pumping Station.It is to obtain the aim of seepage drainage,pressure reduction,subgrade impervious safety by constructing the long and pressure reduction ditch in the front tank,in which to lay the geotechnical cloth and to construct the drainage grit well,in which to put the composite geotechnical cloth bagged grit gravel.The article introduces the design of the geotechnical cloth in the decompression ditch and the composite geotechnical cloth bag.
