摘要
以乌鲁木齐地区杂填土地基道路工程为实例,介绍了杂填土工程特性,对实用地基加固方法进行了分析比选,确定换填法与强夯法为相对较优的地基处理方法。同时,结合乌鲁木齐地区戈壁土特点,确定戈壁土为路基填筑材料和换填材料优先选项,同时对戈壁土压实技术要求进行了明确。
Taking a miscellaneous filling roadbed project of Urumqi as an example, the article introduces the engineering characteristics of miscellaneous filling, analyzes and compares the practical roadbed reinforcement methods, determines the replacement method and the dynamic compaction method as the relatively excellent roadbed treatment methods, and also determines the Gobi soil as the priority option of roadbed filling material and replacement filling material, and defines the Gobi soil compaction technical requirements.
