针对珠江三角洲地区的土、砂、石等地方材料资源的不足,本文介绍了一种新型的软土路基的处理方法—水载预压法及其施工工艺。并通过试验对水载预压的处理效果进行研究,得出水载预压在处理路基沉降方面较其它常规预压法有其独特的优点。同时对水载预压的经济进行评估,发现水载预压法是一种具成本低廉、施工工期短、环保效应好的处理方法。对修筑高等级公路具有十分重要的意义,值得推广应用。
In view of the shortage of local material resources such as soil, sand and stone in the Pearl River Delta region, this paper introduces a new method for treating soft soil subgrade - waterborne preloading method and its construction technology. The effect of preloading on water preloading is studied through experiments. It is concluded that preloading with water has more unique advantages than conventional preloading in settlement settlement. At the same time, it evaluates the economy of water preloading and finds that water preloading method is a kind of treatment method with low cost, short construction period and good environmental protection effect. The construction of high-grade highway has a very important significance, it is worth to promote the application.
