摘要
目前,基础沉降随时间的变化关系一般通过渗透固结理论来计算,由于假设条件较多且影响渗透固结的因素复杂,计算结果常与实际观测值不一致。本文通过分析基础沉降的发生过程及Verhulst模型的特点,提出可以根据施工过程中的观测资料,运用Verhulst模型预测今后不同时刻基础的沉降量,预测实例表明,这一模型具有较好的适应性,可以运用到实际工程中。
In present, the relation between foundation settlement and time always is set up by permeability-consolidation theory, but because there have many presumptive conditions and the factors acting on the permeability-consolidation, it is also very complicated, and the calculation result is always inconsistent with the observed value. By analyzing the process of the foundation settlement and characteristics of Verhulst mode, the foundation settlement of various periods after-construction can be predicted according to observed values in construction period by applying the Verhulst mode. The predicted example shows that the Verhulst mode is very effective and can be applied to the practice
