摘要： 以武汉市王家墩山体公园的堆山工程为研究对象, 介绍了人工堆山工程的地基处理设计方法与山体填筑方案，监测并分析堆山过程中地基沉降、地表水平位移、深层水平位移、超孔隙水压力、土应力和地下水位变化规律。结果表明：在软土地基上进行堆山采用砂石桩地基辅以强夯和堆载预压处理效果良好,山体交汇处是应力集中区域，容易产生较大变形，山体下8m处是一个应力集中区域，宜重点监测,研究结论可为类似的堆山工程地基处理与监测方案提供借鉴参考。

Abstract: Currently, there are few construction experience and design procedures for the large scale manmade hills on soft soils. This paper presents a case history of a manmade hill project in Wangjiadun Theme Park. The soil improvement design as well as the manmade hill construction is introduced in details. A geotechnical instrumentation program was implemented during the construction.  The vertical and lateral deformation of the ground surface, lateral deflection at various soil depths, excessive pore water pressure, total soil stress as well as the groundwater surface are monitored. The results indicated that the sand/gravel drains plus dynamic compaction and surcharge method receives a satisfactory result. The results also show that large lateral deformations are recorded at the intersection area of two hills. A stress concentration zone is observed at depth of 8 meters below the hill.
