| 摘 要： | 根据湖区填土的层次结构和工程特性,结合地基土中附加应力的分布规律,采用碎石桩-强夯联合法能起到较好的加固效果.该法先在填土层中设置好碎石桩体,利用挤密和排水固结的作用使其得到初步加固,然后对荷载影响深度范围内的复合土体进行低能强夯处理,迫使桩体碎石沿径向扩散,形成上部为密实的碎石二合土层、中部为扩径后高置换率复合地基、下部为整体夯密复合地基的三层结构.这种土层结构形式具有较高的强度和整体稳定性,能满足一般建筑物的浅埋扩展基础的要求.图1,表1,参8.

| Abstract: | Based on the structure and engineering properties,combined with the distribution rule of net foundation stress,it could better reinforce artificial soil with gravel pile and dynamic compaction.Firstly,gravel piles in soil were laid for compacting and consolidating soil,then gravel composite foundation was treated with dynamic compaction in order to form three-level soil that is gravel composite soil and high replacement ratio composite foundation and dense composite foundation.The soil structure has higher strength and better stability,which can meet the needs of general buildings.1fig.,1tab.,8refs. |
