摘要
由于各种因素的影响,碎石桩处理液化粉土地基的挤密效果与设计计算结果有较大的差别。通过某高速公路实验段采用碎石桩处理液化粉土路基的实测数据,总结了6个影响碎石桩处理液化粉土地基效果的因素:碎石桩置换率、粉土黏粒含量、粉土埋深、原地基的密实度、场地土的均匀性、施工振动挤密,并详细讨论了这些因素对于实际挤密效果的影响。同时建议应当有一种新的挤密设计方法来综合考虑这些因素的影响。
It is known that there are many factors influencing the compaction effect of stone composite ground,especially in silt subgrade.In this paper,six factors were summed up and studied in details by analyzing the test data on five testing areas of an expressway project in China.It is also proposed that there should be a new designing method in which some of these factors be considered.
