摘要
基于粉煤灰的工程特性 ,可采用高真空击密工法对新近水力吹填的粉煤灰地基进行大面积加固 ,本文主要列举了 2个成功应用实例。在不加填料的情况下显著提高水力冲填粉煤灰的力学性能 ,满足设计要求 ,同时下卧软粘土的工程性质也得到一定程度改善。它具有造价低。
Based on the properties of fly ash fill,high vacuum densification method can be applied to improving of hydraulic fly ash fill.Two successful cases are illustrated.The properties of hydraulic fly ash fill is obviously improved with no sandy fill,then achieve the designing demands.The underlying soft clay is also shown some improvement.The advantages of the method is of low cost and of short period.
