摘要
基于粉煤灰的工程特性和现有地基处理方法的特点,采用高真空击密工法对新近水力吹填的粉煤灰地基进行了加固试验,经过真空排水-击密的多遍循环,在不加填料的情况下显著提高了水力冲填粉煤灰的物理力学指标,满足了设计要求,同时下卧软粘土的工程性质也得到一定程度改善。
Based on the properties of fly ash fill and available ground improvement methods, the improving test of hydraulic fly ash fill was carried out by high vacuum densification method. After several circulation from vacuum drainage to dynamic densification, the properties of hydraulic fly ash was obviously improved with no sandy fill on surface, which satisfied the demands of design. Moreover, the underlying soft clay was also improved to some extent.
