摘要

土压平衡式盾构工法逐渐成为了城市地下隧道建设的主流方法，其刀盘扭矩相对于泥水加压式盾构机的刀盘扭矩大得多，已经成为了盾构工程界普遍关注的一个问题。目前，对于扭矩的计算大多采用经验估算的办法，存在过大的扭矩估算区间，由于施工经验的缺乏以及为了工程施工安全，不得不采用扭矩的上限值来进行盾构装配扭矩的设计，从而造成较大浪费。根据刀盘扭矩的形成机制，分别探讨各组成部分扭矩计算方法，综合后得到盾构机刀盘扭矩的计算力学模型。最后通过一个地铁盾构施工实例验证盾构刀盘扭矩计算力学模型的合理性。

Abstract

The construction method of earth pressure balanced shield has become the one of main trend for underground tunnel construction in metropolis. The torque on cutter head is by far higher than the one of Mud-water Pressure-adding Balance Shield

which is a common concern in the field of shield tunnel engineering. At present

the method of empirical estimation for torque of cutter head is adopted mostly

unfortunately

this method has a too wide estimation interval. For lack of experiences in construction and in consideration of construction safty

man cannot but use the ultimate value of torque to make the design of the assebling torque of shield

thus resulting in great waste in cost. According to the mechanism of torque formation

this paper studies the method to calculate the torques of every composition members respectively and then establish a model for the calculation of the torque on shield machine’s cutter head. Finally

the paper verifies the rationality of the model through an engineering case of shield construction in a subway project..
