摘要
本文基于粘弹性基础梁算法 ,利用粉沙地基上船闸施工过程中各观测点的实测沉陷值 ,采用直接反分析法来反演地基的粘弹性参数 ;实例计算表明 ,反分析方法稳定、有效 ;提供的参数用于仿真计算能很好地模拟整个工程从开挖、施工到正常运行的全过程。
In the paper, based on viscoelastic foundation beam algorithm, making use of the measured settlement values of all monitoring points during the construction process of lock on soft foundation, viscoelastic parameters of foundation are inverted with direct inverse analysis method. Example shows that the inverse analysis method is stable and efficient. The whole process of excavation,construction and operation in a project can be simulated well with simulating computation in which the supplied parameters are used.
