Abstract

Abstract:

Archimedes spiral formula and rules of the cutter arrangement of the shield for the running tunnel from Xueyuan South Road Station to Shuangyushu Station of Line 4 of Beijing Metro are derived on basis of Archimedes spiral arrangement principle and the arrangement of the cutters of the shield for the running tunnel. In addition, optimized cutter arrangement is proposed on basis of analysis and study on the wearing of the cutters. The research results will be useful for the optimal arrangement of shield cutters in similar tunnel projects.

Key words: shield , cutter, Archimedes spiral, arrangement rule, cutter wearing
