市政道路下穿城市复杂区域隧道工程总体方案设计

摘要

通过对康王路下穿流花湖隧道工程复杂建设条件下控制因素分析,提出合理的总体设计方案,旨在探求在复杂建设条件下城市大型隧道工程科学合理的工程全局构思理念.城市道路隧道设计是一个综合性课题,与地形、地貌、工程地质、水文地质、社会人文和环境等多方面因素密切相关,它需要设计者在满足设计规范的前提下,对涉及方案的影响因素和控制条件进行逐步分析,理清主次,结合路网规划、隧道理深、洞口位置及洞外接线、工期等综合考虑,进行多方案比较,从而合理得出最有利的道路方案和隧道方案.%Through the controlling factor analysis of Kangwang Road tunnel passing through Liuhua Lake under complicated conditions,a reasonable general design plan is proposed aiming at exploring scientific and reasonable general engineering concepts for large-scale tunneling under complicated construction condition.Urban road tunnel design is a comprehensive project in close relationship with terrain,topography,engineering geology,hydrogeology,social humanity,environmental and other aspects,which requires the designer to analyze and clarify primary and secondary issues related to plan factors and controlling conditions under the premise of meeting the design specifications so as to determine the most favorable road and tunnel option in light of network planning,tunnel buried depth,portal location and portal outside connection,and construction period.
