| 摘 要： | 针对华润南沙燃机电厂地质较为复杂,回填土下有6~15 m的淤泥层,淤泥为流塑状,未经处理不能作为地基持力层状况,采用3种处理方案:建(构)筑物地基处理采用预应力高强混凝土管桩;室内地坪、检修场地及设备基础下采用水泥搅拌桩处理,处理后的复合地基承载力特征值不小于120 kPa;厂区道路、厂区主要沟道、管线等部位采用高真空击密法,处理深度不小于6.0 m,处理后的软土地基承载力特征值要求不小于100 kPa。经检测,均满足设计要求。

| Abstract: | The geology of Huarun Nansha Gas Turbine Power Plant is very complex. There is silt layer with thickness of 6 to 15meters under the backfill earth. The silt is flowing and can not be used as foundation before being treated. Using PHC for the buildings foundation soit and deep mixing method for indoor ground, repair site and equipment base, the carrying capacity of compsite foundation will not be less than 120kPa;The site of the roads, main channels and pipelines in the power plant will be applied with HVDM,with the depth no more than 6. 0 meters. After being treated, the carrying capacity of soft soils foundation will not be less than 100 kPa. By being testing,all parts meet the design requirement. |
