新疆某引水工程盾构机刀具失效形式及原因分析

Failure Form and Cause Analysis of EPB Shield Cutter in a Water Diversion Project in Xinjiang

盾构机刀具失效会直接影响盾构机掘进效率和施工成本。因此,以新疆某引水工程盾构施工工程为背景,分析某标段砂岩地质条件下盾构机滚刀和切刀失效形式及其成因,并结合工程实际给出相应的改进措施和建议。

The failure of EPB shield cutter directly affects the efficiency and construction cost of EPB shield tunneling.Therefore,taking the shield construction of a water diversion project in Xinjiang as the background,the failure forms and causes of EPB shield cutter under the sandstone geological conditions of a bid section are analyzed,and the corresponding improvement measures and suggestions are given in combination with the engineering practice.
