| 摘 要： | 文中基于软土地基上的园林山体填筑过程中监测数据,分析探讨了经过塑料排水板(PVDs)处理后的软土地基上堆载过程中地基的变形特性,结果表明:PVDs处理的软土地基的变形特性,主要以沉降变形为主;破坏前坡脚水平位移及竖向隆起均存在突变,未有明显征兆;填筑过程中沉降速率预警值采用动态控制;边桩布置位置会影响边桩竖向及水平位移的监测效果,PVDs处理的地基,边桩位移发展模式与天然地基不同。其结论对类似工程有一定参考价值。

| Abstract: | This paper analyzes and explores the deformation characteristic of soft soil foundations during refilling process after dealt with plastic drain plate(PVDs) based on monitoring data during gardening mountain mass refilling on soft soil foundations.The result indicates that the deformation characteristic of soft soil foundations dealt with PVDs is mainly of settlement deformation;horizontal displacement and vertical hunch of slope toe before destruction have sudden changes but there is no obvious omen;pre-wa... |
