摘要
以真空联合堆载预压法软基处治工程实例为基础,通过对施工工法进行深入分析和实践,再根据实际施工经验分析总结路基堆载土填筑施工技术;控制每级路基堆载土填筑厚度,确保软基处理完成后,堆载土顶面标高等于交工面标高,避免进行二次填筑或挖除多余土方造成工程延期和增加施工成本现象。
Based on soft soil subgrade treatment engineering by vacuum combined with surcharge preloading, the construction process is deeply analyzed and practiced. According to the practical construction experience,filling technology of heaped load soil for deep soft soil subgrade is analyzed and summarized. The thickness of filling layer of each stage heaped load soil for subgrade is controlled,which ensures that the elevation on the top of heaped load soil is equal to the elevation of the acceptance surface, avoid engineering delayed and construction cost increased because of secondary filling and excavating redundant earthwork.
