为了研究机场高填方地基变形规律及稳定性状况,减小工后沉降,保证施工期、运营期的稳定安全,采用有限元软件ANSYS,选取重庆江北机场南侧工程区高填方工程作为研究对象,模拟实际施工加载过程,并对高填方地基变形及稳定性进行分析评价。研究结果表明:高填方地基沉降变形最大处位于坡顶附近,并随高度减小而减小;水平位移最大处位于边坡腰部,呈现“中间大两头小”的趋势。总的来说,高填方工程在施工过程中要特别注意顶部沉降及腰部鼓出,确保工程质量。
In order to study the law of deformation and stability of high embankment at airport, reduce post-construction settlement and ensure stability and safety during construction and operation period, finite element software ANSYS was used to select the high-fill project in the south of Chongqing Jiangbei Airport Object, simulate the actual construction loading process, and analyze and evaluate the deformation and stability of high-fill foundation. The results show that the maximum settlement of settlement on the high embankment is located near the top of the slope, and decreases with the height decreasing. The maximum horizontal displacement is located at the waist of the slope, showing a tendency of “middle big two small ”. In general, special attention should be paid to the top subsidence and bulging of the waist during the construction of the high-fill project to ensure the quality of the project.
