摘要
堆山工程是为了有效处理疏浚河道产生的废土,进行生态城市建设中一种新的工程类型,人工山体地基沉降变形规律及沉降量是评价其稳定性非常重要的指标。以通州区综合治理工程中南山和北山为工程背景,详细分析了南山和北山地面水平位移、地面沉降和深层土体水平位移,综合评估了堆山工程在施工阶段的沉降变化特征。结果显示:南山和北山的地面沉降呈整体下降趋势,但位于周边的土体有微小的反弹;地面水平位移有向山体外移动的微小趋势,随着深度的增加,深层土体水平位移向山体中心有较小的位移。
Mountain piling project is a new type of project in order to effectively deal with the waste soil produced by dredging river and carry out ecological city construction. The settlement deformation law and settlement amount of artificial mountain foundation are very important indexes to evaluate its stability. Based on the engineering background of Nanshan and Beishan in the comprehensive treatment project of Tongzhou District, the ground horizontal displacement, ground settlement and deep soil horizontal displacement of Nanshan and Beishan are analyzed in detail, and the settlement variation characteristics of mountain piling project in the construction stage are comprehensively evaluated. The land subsidence of Nanshan and Beishan shows an overall downward trend, but the surrounding soil has a slight rebound;with the increase of depth, the horizontal displacement of deep soil has a small displacement to the center of the mountain.
