摘要：

卵砾石层于潜盾隧道开挖工法中，地质的不均匀性及巨大的砾石，是影响潜盾工程推进之主要因素，其掘进过程问题繁杂，被列为潜盾工法困难地层之一，国内外对于此地层施工经验稍嫌不足，因而无法有效掌握地质特性，顺利推展潜盾机之掘进工作。台湾电力公司竹工超高压线路洞道工程，位于新竹县湖口乡，计画洞道沿线均为卵砾石层，隧道长达8.4 km，砾石含量50%~80%,针对掘进过程中遭遇到种种困难，诸如切刃盘及切刃齿磨损严重，以开舱改造切刃盘方式对应、量测磨耗量及管理掘进数据与加泥材调整等做详细整理与说明，以利日后潜盾工程遭遇卵砾石层时做为参考。

Abstract:

Geological nonuniformity and large boulder have been the key influence factors for shield tunneling in gravel layers. Gravel layer has also been recognized as one of the difficult grounds due to its complicated problems during excavation. Unfortunately, lacking in experience for shield tunneling in such ground leads frequently to incapability of treating the geological characteristics properly and boring work as well. The case studied is Taiwan Power Company Hsichu Industrial Park Extra High Voltage Transmission Line Underground Cable Tunnel Project, which is located in Huko Township of Hsinchu County, with a total length of 8.4 km. The designed route passes through a gravel layer, with boulder content up to 50~80%. This article compiled and described the problems encountered during excavation phase, such as serious wear and tear of disc and cutter, repair and modification of disc, wear survey, excavation management system, adjustment of polymer to lubricate the soil, etc.

Key words: gravel layer, shield tunnel, cutter disc
