摘要

在都會區興建地下捷運系統時，為避免隧道開挖對於都會區的交通及環境造成太大衝擊，世界各國廣泛的採用潛盾施工法。台灣地區已有興建台北捷運系統的豐富經驗，目前正積極興建高雄捷運系統，本文旨在進一步探討地層性質的變化對於潛盾隧道襯砌環片受力之影響，即研究襯砌環片勁度與周圍地層勁度兩者之互制影響，以期明確掌握襯砌環片結構受力特徵，為潛盾隧道設計與施工提供合理的參考依據。

MRT system is very popular in the metropolis area. To avoid transportation and environment impact on the function of the city during the MRT is being built, shield tunneling method is widely adopted in many countries. In Taiwan, the experience of Taipei MRT is being applied to Kaohsiung MRT which is still under progress at the moment. Due to the difference of soil properties, the settlement and lining forces caused by the excavation at some part of Kaohsiung MRT may larger than that of Taipei MRT. To investigate the reason for this, the interaction of soil and tunnel lining is studied on this paper. It is expected that the results and suggestions described in this paper would be helpful in gaining the ability of analysis so that more effective design can be developed for such problem in the future.
