摘要
结合滨海深厚软土地质特点和真空联合堆载预压及强夯处理软土地基的机理,计算、试验和研究了真空联合堆载预压及强夯在处理滨海深厚软土地基时地基土的沉降、强度和物理力学等参数的变化规律。工程实践表明真空预压下静动排水固结法处理滨海深厚软土技术可行,达到料场对地基土强度和变形的要求,是一种切实可行、科学经济的地基处理方法。
Combined with the coastal geological characteristics of deep soft soil and Mechanism of vacuum combined with surcharge preloading and dynamic consolidation for soft soil foundation treatment,The variation law of settlement,strength and physical mechanics parameters of foundation soil in treatment of deep soft soil foundation by vacuum combined with surcharge preloading and dynamic compaction were calculated,tested and researched The Engineering practice shows that It is feasible to treat deep soft soil by static and dynamic drainage consolidation method under vacuum pressure,which achieved the requirements for strength and deformation of foundation soil by material field,and it is a practical,scientific and economic method for foundation treatment.
