m。该楼基础坐落在地势低洼地带(由于住宅区总体管网已形成,无法重新选址)。地基土质经现场取样为可塑性粘土(E=800～1600t/m~2),地基承载力为R=130MPa,达不到设计要求。为使主体结构既安全可靠、方便施工,且能降低工程造价,我们采用了片石垫层细砂灌缝,回填2∶8三合土级配砂石和滚动碾压等施工方法进行了地基处理。 m. The foundation of the building is located in a low-lying area (because the overall pipe network in the residential area has been formed, it cannot be relocated). The ground soil was sampled as plastic clay (E=800~1600t/m~2) on site, and the bearing capacity of the foundation was R=130MPa, which could not meet the design requirements. In order to make the main structure safe and reliable, convenient construction, and can reduce the project cost, we have adopted the construction method of fine stone sand cushion filling, backfill 2:8 sand grading and roller rolling and other construction methods for foundation treatment.
