一、概述塑料板排水法是垂直排水预压法的一种,塑料排水板技术也是土工合成材料技术的一个分支。该法源出于纸板排水法,它与(袋装)砂并排水法同属于垂直排水法范围,经过近60年的发展,该法已广泛应用于堆载预压,真空(降水)预压,强夯等软基加固工程中。另外经过国内学者的理论计算也不断完善。其应用的范围也不断扩大。它可作为消除打桩挤土振动产生的超孔隙水压力的措施,避免对周围环境造成的不利影响。可以看到,塑料板排水法正越来越多地应用于其它工程建设项目中。
I. Overview Plastic plate drainage is a vertical drainage preloading method. Plastic drainage plate technology is also a branch of geosynthetics technology. The method is based on the paperboard drainage method, which belongs to the vertical drainage method in the same way as the (bagged) sand-drainage method. After nearly 60 years of development, the method has been widely used in preloading of preloading and vacuum (precipitation) preloading. , Intensity and other soft-base reinforcement projects. In addition, the theoretical calculations of domestic scholars have also been continuously improved. The scope of its application is also expanding. It can be used as a measure to eliminate the excess pore water pressure generated by vibration of pile-squeezing soil and avoid adverse effects on the surrounding environment. It can be seen that the plastic plate drainage method is being applied more and more in other engineering construction projects.
