摘要
据城市发展的需要,市政交通设施包括隧道或管道穿越及沿河的情况成为了河道护岸加固改造的一个重要因素。隧道及管道施工时将引起土体扰动变形,对周边河道护岸结构产生影响。在周边环境复杂的地区这种影响可以通过采取一定的土体加固措施后减少对护岸的影响。通过实例的数值模拟的方式预测了盾构施工期对河道护岸的影响,并分析土体加固后的效果,为今后类似的工程提供参考。
According to the needs of urban development, urban traffic facilities such as tunnel or pipe crossing and river became an important factor of river bank reinforcement and reconstruction. The soil disturbance and deformation caused in the construction of tunnel and pipe exert an influence on the surrounding river bank structures. This kind of influence on the river bank can be reduced after the certain soil reinforcement measures are taken in the areas of complex surrounding environment. The practical numerical modeling mode can forecast the influence of shield construction period on the river bank. The effect of reinforced soil is analyzed. The relative experience can be referred for the similar projects in the future.
