- 摘要:
- 长输管道建设中由于对边坡的不合理开挖和加载，以及大气降水、河流冲刷、风化、岩性等内在因素影响，出现大量边坡失稳情况，并且表现形式复杂。在边坡治理以管道安全作为首要目标的前提下，针对管道作为线性构筑物具有一定弹性变形能力的特点，通过分析边坡的变形方式、变形诱发因素、变形机理和对管道运营及施工的影响，提出有针对性的、综合性的治理方案和措施，为管道选定线和建设施工中发生的边坡失稳处理提供技术借鉴。

Elaborated are several kinds of side slope instability conditions occurred frequently during construction and operation of lone-distance pipeline. Analyzed are forms of slope deformation, inducing factors, deformation mechanism and effect of side slope deformation on construction and operation of pipeline and specific, reasonable and feasible prevention and treatment measures are put forward, which will provide certain reference for prevention and control of side slope instability occurring probably during route selection and construction of pipeline.
