摘要
详细介绍了含承压水地层真空预压施工工艺,打设塑排板采用撕膜和非撕膜施工工艺相结合,既可靠又经济;阐述了在真空预压过程中若砂垫层失效后如何采取有效的补救措施;提出了采用四周循环蓄水处理夹砂层漏气的办法,实际证明,效果良好。介绍了若干其他施工工艺,可为类似地质条件下的真空预压施工作参考之用。
The construction technology of vacuum preloading in the stratum with confined water is describde in detail. It is safe and economic that the technology of ＇tearing membrane＇ is combined with the ＇non-tearing membrane＇ while driving PVDs. The effective method is elaborated while repairing the loss of sand cushion. It is presented that recycling water could deal with the leakage of deep soil in vacuum preloading. Lastly other important technologies such as outlet assembly, elimination of typhoon damage and the problem of excavation of interlayer are put forward.
