| 摘 要： | 巫山县新城污水处理厂高填方地基的最大填方高度为75m,填筑方量约56.7万m3.当三峡水库蓄水至175m时,填筑体绝大部分处于库水位以下,设计中必须考虑填方体的整体稳定性和湿化变形引起高填方不均匀沉降对直径为70m的氧化沟的不利影响.在污水处理厂厂区建(构)筑物基础设计中,采用短刚性桩复合地基将部分荷载由桩传递到深部强夯层面上去,减少氧化沟边缘与中心点的不均匀沉降,并有效地减少总沉降.本文通过巫山县新城污水处理厂高填方地基工程实例,详尽地介绍了高填方工程填筑方案的选择与设计.

| Abstract: | The high fill of Wushan Municipal Sewage Treatment Plant has a maximal heigh of 75m. and a volume of 56. 7ten thousand cubic meters. When the TGP's water level arrives at 175m,the most part of the high fill will be submerged, it is necessary for designer to consider the overall stability, the differential settlement and the slaking deformation of the high fill due to wetting. The better choice for the foundation of the Sewage Treatment Plants construction works is the rigid short pile's composite foundation, which can transmit some of the applied load to the well soil's planes by dynamic compaction below the ground surface and reduce the differential settlement of the storage structure with 70m in diameter. Selection and design plan of construction of the high fill of Wuhan Micnicipal Sewage treatment plant are introduced in detail by the paper. |
