盖挖顺作法在深圳地铁科学馆站的应用

结合深圳地铁一号线科学馆站的设计 ,介绍盖挖顺作法在地铁车站施工中的应用。科学馆位于深圳市中心区深南中路上 ,该区环境优美、交通繁忙、商业发达、居民密集 ,地铁车站的施工对该区的影响极大。本站采用盖挖顺作法施工 ,在保证路面交通、施工安全、车站功能、工程质量以及施工工期等方面均取得较好的实际效果 ,并且土建投资得到有效地控制。盖挖顺作法施工时对周边的环境影响小 ,获得良好的社会效益。盖挖路面系应围绕路面车辆通行能力、施工工序以及临时路面结构受力体系进行设计。

Application of Cover and Cut (bottom-up) Method to Shenzhen Metro Construction

An introduction is given to application of cover and cut (bottom\|up) method to metro station construction based on design of Science Museum Station of Shenzhen Metro Line 1. The Science Museum is located at downtown Shenzhen, where features graceful environment, heavy traffic, prosperous commerce, and dense residential buildings. Therefore, construction of metro station will cause great impact on this area. The adoption of cover and cut (bottom\|up) method brought good effect in guaranteeing normal traffic, construction safety, station functions, engineering quality, and construction period, as well as effective control of construction investment. The method also resulted in good social effect for minor impact on surrounding environment. In this method, design of pavement system should focus on carrying capacity of road surface, construction sequence, and force structure of temporary pavement structure.
