菲律宾卡利瓦大坝项目TBM选型研究

TBM Selection of Kaliwa Dam Project in the Philippines

为选择菲律宾卡利瓦大坝项目输水隧洞施工合适的TBM类型,笔者从地质条件、工期、施工安全与环境和经济性等方面对敞开式TBM和双护盾式TBM进行比较研究,最终选择双护盾式TBM作为输水隧洞TBM洞段的施工设备。研究成果可为具有施工隧洞长、洞径小、地质条件较差等特点的隧洞施工如何进行TBM选型提供参考。

In order to select the appropriate TBM type for the construction of the water conveyance tunnel of the Caliwa dam project in the Philippines,the author makes a comparative study of the open type TBM and the double shield TBM from the aspects of geological conditions,construction period,construction safety,environment and economy,and finally selects the double shield TBM as the construction equipment for the TBM section of the water conveyance tunnel.The research results can provide reference for TBM selection in tunnel construction with long construction tunnel,small tunnel diameter and poor geological conditions.
