摘要：【中文】本发明是一种基于吹填试验的珊瑚砂次压缩系数的测量方法，该方法对于时间空间不均匀吹填珊瑚砂底层次压缩系数提供了一种测量计算方法，吹填海工程不同区域往往是不同时间吹填，不同厚度吹填，造成不同区域地层固结程度不同，后期沉降差异较大，采用理论难以较准确的计算出其最终沉降量，该计算方法充分利用场地历史条件、试验数据，最大限度的回归历史，模拟地层自固结沉降完成历史过程，对比新旧吹填、厚度不等处理后的地层沉降数据，充分分析地层历史差异性，当下数据差异性，得出历史与当下共性，进行对比分析，进而得出更加符合实际的次压缩系数。 【EN】The invention relates to a method for measuring secondary compressibility of coral sand based on a hydraulic fill test, which provides a measuring and calculating method for the secondary compressibility of coral sand at the bottom of hydraulic fill coral sand with nonuniform time and space, different areas of hydraulic fill sea engineering are always hydraulic filled at different times and hydraulic filled at different thicknesses, which causes different consolidation degrees of strata in different areas and larger later settlement difference, the final settlement amount of the hydraulic fill coral sand is difficult to calculate more accurately by adopting theory, the calculation method fully utilizes the site historical conditions and test data, maximally regresses the history, simulates the historical process of completing the self-consolidation settlement of the stratum, comparing the stratum settlement data after the treatments of new and old hydraulic reclamation and unequal thickness, fully analyzing the historical difference of the stratum, and comparing and analyzing the current data difference to obtain the history and the current commonality so as to obtain the secondary compression coefficient which is more in line with the reality.
