摘要 昆明市轨道交通环城南路站—得胜桥站盾构区间设计线形复杂,工程地质条件差,地表建筑物密布,居民密集,房屋建筑多属老旧危房,且无抗震措施。盾构施工风险极高,施工难度极大,被列为昆明市轨道交通工程的重大风险源。根据盾构成功地连续穿越环得区间重大风险源的施工经验,总结了在复杂线形及地质条件下的盾构施工技术。 The designed interval line of the shield between Huancheng Road (South) Station and Deshengqiao Station of Kunming Rail Transit is complicated with poor engineering geological condition, intensive surface structures and residents, and most of the houses and buildings are old and dilapidated without any earthquake proofing measures. Therefore the shield construction there is subject to high risks and large difficulties, thus included into the major risk sources in the rail transit project of Kunming. Based on the construction experience of the shield successfully passing this interval major risk source continuously, this paper summarized the shield construction technology under such complex line type and geological conditions.
