为解决京沪高速铁路某段合格填料缺乏的问题,通过总结掺入粉煤灰、石灰、水泥改良填料的机理,利用当地资源通过试验研究不同掺量的水泥、石灰、粉煤灰对填料含水率、无侧限强度和最大干密度等参数影响,设计改良方案,通过现场填筑,确定满足设计要求、经理合理的方案,可供类似工程参考。 In order to solve the problem that some qualified fillers in the Beijing-Shanghai high-speed railway are lacking, by summarizing the mechanism of improving the fillers by using fly ash, lime and cement, the local resources were used to study the effect of cement, lime and fly ash Rate, unconfined strength and maximum dry density and other parameters, the design of improved programs, through on-site filling to determine the design requirements to meet the manager reasonable program for similar projects for reference.
