通过现场较大规模的测试研究和整理分析 ,首次获得了无粘结预应力筏板基础地基反力的第一手资料 ,揭示了这种基础地基反力的一些分布规律和无粘结预应力对地基反力分布的影响和作用 ,这些成果校验了该大楼基础的设计 ,亦可供同类基础设计时参考。同时在基底反力测试研究中 ,探讨了大直径土压力盒室内和现场相结合的综合标定方法 ,可为土压力现场测试时借鉴 Through the large-scale on-site test and analysis and consolidation analysis, the first-hand information on the reaction force of unbonded prestressed raft foundation is obtained for the first time, revealing some distribution laws of this foundation and unbonded prestress On the distribution and impact of the foundation reaction force, these results verify the design of the building foundation, but also for reference to similar basic design. In the meantime, the comprehensive calibration method combining the indoor and the field of large diameter earth pressure box is discussed in the research of the substrate reaction force test, which can be used for the field test of earth pressure
