| 中文摘要: |
| 以武汉市园博会垃圾土地基堆山工程为研究对象,针对其堆山工程分区特点,制定监测方案,并选取代表性区域,分析了山体表面沉降、地基土沉降与上部填土高度、地基土分层沉降量与深度、深层水平位移与深度随时间的变化规律,研究结果表明:山体表面沉降变形增长曲线可分为快速增长、平稳增长、缓慢增长3个阶段,堆山填土对地基土变形的影响范围约为2倍的填土高度H。研究了一种基于变形速率差值更新迭代的监测预警方法,解决了采用单一变形指标进行监测预警的弊端。研究结论可为类似的堆山工程设计和施工提供借鉴参考。 |

| Taking the project of the landfill piled mountain garden expo in Wuhan as the research object, there are monitoring scheme according to the regional characteristics of its piled mountain engineering. The law of changing with time is studied by selecting representative regions, which contains the mountain surface subsidence、settlement of foundation soil and thickness of upper fill、stratified settlement of foundation soil and depth horizontal displacement. The results show that the slope surface settlement deformation growth curve can be divided into three stages:rapid growth, steady growth and slow growth. And the influence range of rockfill on the deformation of foundation soil is about 2 times the fill height. A monitoring and warning method based on updating and iterating deformation rate difference is studied. Therefore, the results of this study can be used for reference in similar engineering design and construction. |
