现有地基沉降预测模型多数是几何统计模型,参数意义不够明确,而Asaoka方程具有明确的理论基础,在工程中得到了广泛应用。针对实际应用中,Asaoka方程存在的两点不足:递推公式未考虑误差传递效应和对于等时间间隔沉降观测数据无法直接应用,对其进行了详细的分析,同时提出了相应的改进方法,建立了非等间隔Asaoka方法。将两种改进方法应用于实际工程中,结果显示两种改进方法是有效的。
Most of the existing subsidence prediction models are geometric statistical models, the meaning of parameters is not clear enough, while Asaoka equation has a clear theoretical basis, which has been widely used in engineering. For practical applications, the Asaoka equation has two disadvantages: the recursion formula does not consider the error transfer effect and can not be applied directly to the observation data of equi-time subsidence, and has been analyzed in detail. At the same time, some corresponding improvement methods are put forward to establish The non-equal interval Asaoka method. Applying the two improved methods in practical engineering, the results show that the two improved methods are effective.
