介绍Asaoka方法的步骤和内容 ,以深圳机场实验区和深圳福田保税区软基处理工程的现场测试数据为基础 ,采用Asaoka方法和指数曲线三段法对地基最终沉降进行了推算 ,并对不同的推算方法进行了分析比较。采用指数曲线三段法推算需要较长的现场实测资料才能反映瞬时、主固结、次固结沉降的变化过程 ,Asaoka方法推算过程中对沉降过程的阶段性依赖不明显 ,利用较短时间的观测资料就能够得到较为可靠的最终沉降的推算结果 ,且可直接计算出次固结沉降 ,具有较高的应用价值
The steps and contents of Asaoka method are introduced. Based on the field test data of Shenzhen Airport Experimental Zone and Shenzhen Futian Free Trade Zone Soft Foundation Treatment Project, the final subsidence of the foundation is estimated by Asaoka method and exponential curve three-segment method. Methods were analyzed and compared. The exponential curve three-segment method requires long-term field data to reflect the process of instantaneous, main consolidation and secondary consolidation settlement. The staged dependency of settlement process in Asaoka method is not obvious, and the short-term Observation data can be more reliable final settlement of the projections, and can be directly calculated sub-consolidation settlement, has a high value
