【摘    要】:為了優(yōu)化盾構(gòu)管片開孔臨時支撐系統(tǒng),依托以色列特拉維夫綠線項目,對新型環(huán)形鋼支撐支護(hù)形式進(jìn)行了數(shù)值模擬理論分析。驗證了此結(jié)構(gòu)樣式具有良好的結(jié)構(gòu)穩(wěn)定性、經(jīng)濟(jì)性、便捷施工性,可為類似管片破除臨時支護(hù)或者管片加固提供一種新的解決方案。

【關(guān)鍵詞】:盾構(gòu);管片開孔;環(huán)形鋼支撐;支護(hù)措施

【Abstract】:To optimize the temporary support system for tunnel segment openings, a new type of circular steel support was analyzed by numerical simulation based on Tel Aviv Green Line project. It is proved that this structure style has good structural stability, economy and convenient construction, and can provide a new solution for similar temporary support or segment reinforcement.

【Key words】:tunnel shield; segments opening; circular steel support; support measures

盾構(gòu)區(qū)間的附屬結(jié)構(gòu),例如聯(lián)絡(luò)通道、區(qū)間通風(fēng)井、 雨水泵房等,通常采用傳統(tǒng)暗挖法施工[1],施工前需要破除已拼裝好的盾構(gòu)管片,再實施洞內(nèi)開挖,施工相關(guān)結(jié)構(gòu)。(剩余3828字)
