南水北调工程北京段PCCP管道施工沿线的地质灾害与防治

重大城市线性工程施工可能会诱发或面临一系列的地质灾害，对其灾害特征、危害及防治方法进行研究具有重要意义。以南水北调工程北京段PCCP管道施工为例，在分析其地质环境背景、地质灾害类型、基本特征、危害性及影响范围的基础上，归纳总结了针对不同类型地质灾害所采用的施工防治措施和方法。重点对施工沿线主要地质灾害如边坡崩塌、特殊地基处理和地面沉降做了深入的探讨。研究成果对PCCP管道后续工程建设和工程运营维护具有一定的现实意义，是对线性工程地质灾害防治进行的有益的探索。

The geohazard and prevention along PCCP pipeline in Beijing area, China as a section of South-to-North water diversion project.

It's possible to encounter some geohazards during the consctruction of civil linear engineering project, so it's quite important to have a thorough understanding for its damage, features and prevention measures. This paper gives a sample of geological background and geohazard problems analysis of the PCCP pipeline project in beijing area as a part of South-to-North water diversion. It aims to analyze hazard distribution and development characteristics of pipeline construction, and also introduces the geohazard types and how to control geohazards including landslip, special groundwork treatment, ground depression and so on during actual construction. The authors also go into how to analyze and control geohazard in line shape engineering project.
