涉地铁建设的原水管道改迁实例分析

Study on Case of Raw Water Pipeline Relocation Related to Subway Construction

摘要:

随着城市经济与建设的发展，原本远离城市中心区的原水管逐渐进入城市建成区，因城市发展建设难以避免，造成原水管的改迁，且日趋频繁。以深圳市轨道交通某线工程为背景，分析探讨涉地铁建设原水管改迁的必要性和唯一性，并进行安全性论证，制定安全稳妥的改迁方案、接驳方案以及监测方案，辅以有限元软件PLAXIS模拟分析地铁车站建设对原水管的影响，验证改迁方案的可行性，以求最小程度影响城市供水安全。为类似因地铁建设造成的原水管改迁工程提供技术参考。

Abstract:

With the development of urban economy and construction, the raw water pipeline far away from the urban central area gradually enters the urban built-up area. Due to the inevitable development and construction of cities, the relocation of raw water pipelines is becoming increasingly frequent. Taking a project of rail transit in Shenzhen as the background, the necessity and uniqueness of the raw water pipeline relocation related to subway construction are analyzed and discussed, and the safety is demonstrated. The safe and reliable relocation schemes, the connection schemes and the monitoring schemes are formulated, and the finite element software PLAXIS is used to simulate and analyze the impact of subway station construction on the raw water pipelines. The feasibility of the relocation schemes is verified to minimize the impact on the safety of urban water supply. The useful reference is provided for the similar raw water pipeline relocation projects related to subway construction.
