摘要
基于贵州瓮安至开阳高速公路开州湖特大桥主塔位置研究实例,提出主塔位置选择是一个系统工程,应从地形地貌、地层岩性、地质构造、不良地质、岸坡稳定性分析、不同主塔位置所带来的治理难度、环保等因素出发,进行多个主塔位置比选,选择技术可靠、投资最优、长期稳定的主塔位置.研究表明:瓮安岸K35+525、开阳岸K36+625适合设置主塔,为最优方案.为复杂艰险山区公路桥梁主塔选址工作提供借鉴.
Abstract
Based on the case study of the main tower location of Kaizhou Lake Grand Bridge,this paper proposes that the selection of main tower location is a system engineering,which should be considered from the perspectives of topography,stratum lithology,geological structure,unfavorable geology,bank slope stability,management difficulty brought by the main tower location,and environmental protection.Multiple positions should be compared,and the position with reliable technology,optimal investment and long-term stability should be selected.The research shows that K35+525 of Weng'an side and K36+625 of Kaiyang side are suitable for setting the main tower.This paper has provided reference for the site selection of the main tower of highway bridges in complex mountainous areas.
