摘要:

岩土本身的诸多不确定性和沉井施工开挖的不均匀性,使得沉井在施工过程中的受力计算复杂化.对沉井下沉施工进行了力学分析,提出了考虑不均匀开挖时刃脚塌面上土体的极限承载力的计算方法,并根据耗散函数的拉格朗日方程建立沉井结构下沉的动力学模型,并用工程实例进行了验证,结果表明所建立的力学模型可以很好地预测一定开挖量下的下沉量.

Abstract:

Many uncertainties in the rock and soil itself and the inhomogeneity of the excavation of the sunken well complicate the calculation of the force of the sunken well during the construction process. The mechanical analysis of sinking construction is carried out, a calculation method is proposed considering the ultimate bearing capacity of soil on the collapse surface of the edge foot during uneven excavation, and the dynamic model of sinking structure is established according to the Lagrangian equation of the dissipation function, and the engineering examples are used to verify that the established mechanical model can well predict the subsidence under a certain excavation amount.
