盾构隧道设计方法研究现状及展望

Abstract

随着地下空间开发利用高潮的来临，为了满足在市区等繁华地区以及环境特别苛刻的区域建造隧道的要求，国内外不断开发出新的施工技术，然而，目前盾构隧道的设计仍然采用传统方法，如修正惯用设计法、梁-弹簧模型法、多铰圆环法等。但有些情况下，传统的设计方法不能完全适用于当下的盾构法施工新技术。因此，为了更好的协调盾构技术的设计和施工，需要完善并创新盾构隧道设计方法。本文概括介绍了盾构隧道设计方法的研究现状，并指出仍需进一步完善的方面。With the arrival of the climax of the development and utilization of underground space, new con-struction techniques were continuously developed to construct tunnels under more severe condi-tions. However, present design techniques sometimes cannot appropriately reflect the construction techniques. Traditional design methods were still used, such as uniform rigidity ring model, beam spring model, multi-hinge ring model, etc. On account of the well-balanced progress between construction and design in the shield tunneling method, an innovation of the design technique is required. This paper shows an outline of the design technique of shield tunnel at present and improvements required for design technique.
