玄武湖水底交通隧道施工方案的比选优化

Contrast and optimization of construction schemes of Xuanwu lake subaqueous highway Tunel

本文用系统分析的思想。对玄武湖水底交通隧道的两种施工方案（明挖法与盾构法）进行了比选，并对明挖法方案进行了优化，最后确定了最佳方案——箱涵顶进加筑堤开槽埋管方法。

Based on the thought of systematic engineering analysis,two working schemes(opencut and cover method,shield method) of Xuanwu Lake Subaqueous Highway Tunnel are contrasted and evaluated in this paper.The opencut and cover method is optimized by the authors.According to this paper,the optimum scheme is the dike construction and pipe burial method with box culvert jacking techniques.
