在软土地区利用淤泥质土进行人工堆山,地基处理方案和堆土方案的设计非常重要。以某拟建堆山工程为例,通过理论分析和三维有限元数值计算,论证了地基处理和堆土填筑的技术方案。地基处理设计以地层强度的增长为主要目标,综合地基土层的性质、工程造价和建设周期等因素,根据不同区域的堆土高度选择不同的地基处理形式。为确保山体填筑过程的稳定,通过三维有限元数值分析方法,计算山体稳定性和地基沉降,验证和调整设计参数,预测最终沉降,达到设计方案最优化的目的。

When artificially piling mountain with muddy in soft soil areas,the design for foundation treating and earth piling scheme is very important.Here,taking a mountain piling engineering for example,the technical scheme for foundation treatment and bulldozing filling is analyzed and demonstrated through theoretical analysis and 3-D finite element calculation.In the design for foundation treatment,the increasing of formation strength should be taken as a main aim,some factors as the nature of foundation soil,project cost,construction period and so on should be taken into account comprehensively,then the appropriate forms of foundation trentment are selected according to the bulldozing height of different regions.In order to assure the stability in hill filling progress,the 3-D finite element analysis method is used to calculate the mountain stability and foundation settlement,verify and adjust the design parameters,and predict the final settlement,at last,the design optimization is achieved.
