摘要
近代海相沉积的软土 ,土层厚度大 ,层次结构复杂 ,工程性能和抗液性能较差 ,一般不宜直接作建筑物地基使用 ,事先必须对其进行加固处理。针对台山电厂海滩建筑地基的工程特点 ,采用振冲碎石桩能有效地加固松散砂层和淤泥 (质 )土层 ,提高其承载力 ,减少不均匀沉降 。
In general,ancient marine deposit soft clay couldn't be used in natural state and must be improved,because it has big thick in stratum,complex constructure in stratum suguence,and less bettery property in engineering and anti liquifying.In view of the engineering features of marine shore foundation soil,the method of vibro replacement stone column is efficient in consoliding loosen sand and mucky soil,increasing its bearing capacity,reducing uniformaty settlement and resisting proventing soil liquifying.
