摘要
通过对大型灌溉水源工程1500 m^3水池软弱地基进行换填处理设计,计算换填垫层在不同工况下,砼水池在软弱地基上的承载力和变形。优化必选最佳的组合参数,再强夯处理,结合地基处理技术规范,提出解决中小型砼水池软弱地基的处理方法。结果表明,换填和强夯法处理软弱地基不但满足工程质量和地基承载力要求,而且具有良好的经济效益。
Through a replacement design of the soft foundation of 1500 m^3 pool of the large-scale irrigation water source project,the bearing capacity and deformation of the pool under different conditions were calculated.The best combination parameters were optimized,and then strengthen the treatment was finished.Combined with a technical specifications of foundation treatment,a treatment method to solve the weak foundation of small and mediumsized sluice pools was proposed.Research results showed that the economic benefits of soft foundation treatment under replacement and strong tamping method were good and it met the project quality and foundation bearing capacity requirements.
