海底隧道复合地层盾构掘进刀具磨损原因分析及对策

Analysis and Countermeasure of Abrasion of Shield Cutter in Subsea Tunnel with Compound Stratum

海底隧道盾构掘进由于复杂的地质情况及不可预测的因素较多,容易对盾构机刀具造成严重的磨损,而海底隧道盾构施工在国内工程案例相对比较少,缺乏海底盾构施工的经验,通过总结海底盾构掘进施工经验,刀具磨损的原因及对策,希望对相关海底盾构掘进施工有所借鉴。

Due to the sophisticated geological conditions and unpredictable factors shield drivage will be encountered undersea,the shield cutter suffers more from abrasion. However,related construction case is relatively few in China,leading to lack of experience of this area. The reasons and measures of the abrasion will be discussed in this essay based on experience of shield tunneling construction,hoping to offer solution to undersea shield drivage.
