摘  要:
我国石油天然气储运设施建设正在高峰期,管道不可避免地通过大量的梯田或坡耕地地区,造成管道沿线较严重的水土流失和耕地面积的减少。针对输油气管道敷设与梯田的关系,探讨了输油气管道对梯田的破坏特征及力学机理,提出了管道开挖前'取一定厚度的表层土,并回填为梯田最上层'的回填方案,确保梯田土壤肥力,并根据影响梯田稳定性的主要因素提出综合加固梯田,防止水土流失的方案。

摘  要:
During the times of building long distance oil and gas pipeline at high speed,it leads to a lot of loss of water and soil and the area of field.In according to the relative of pipeline and terrace,their characteristics and mechanism are analyzed.The method of mitigating the hazards is given as follows: dig the surface soil and deposit at some place before the engineering of pipeline ditch,backfill as the top layer to assure the good use of the wealth soil be applied.Based on the computing of the stability of terrace,a compostive system is provided to reinforce the terrace and control the loss of water and soil.
