土压平衡盾构螺旋输送机力学模型简析

  • 摘要: 利用土压平衡原理,建立了土压平衡盾构螺旋输送机的力学模型,推导出螺旋输送机底部压力在静力平衡条件下的力学表达式,讨论了螺旋输送机底部压力与其设备参数及渣土性质参数的关系,为合理设计、改造、选用和评价土压平衡盾构螺旋输送机提供了一个简便的方法.

     

    Abstract: A mechanical modelof the earth pressure balance shield screw conveyor is built byconsidering the earth pressure balance. An expression of thepressure at the bottom of the screw conveyor is obtained according to themodel. The relationships between the bottom pressure and theparameters of the screw conveyor and the residual soil are discussed. The expressionprovides a simple method to design, improve, select and evaluate the earthpressure balance shield screw conveyor.
