保神高速公路不稳定斜坡地区地质选线研究

随着山区高速公路建设的不断增多，地质选线成为成本控制的关键，地质灾害成为选线的控制因素之一。不稳定斜坡作为山区高速公路建设中最常见的地质灾害，因选线阶段未能及时避让或采取合理的治理措施，常常在高速公路的建设和运营阶段造成巨大安全隐患及经济损失。结合保神高速公路在不稳定斜坡区选线的经验，归纳总结了在不稳定斜坡地段选线的基本原则。

Research of Geological Route Selection in the Potential Landslides Areas on Baoshen Highway

With the increasing highway construction in mountainous area, geological route selection in geological disaster areas become the key of cost control, geological disasters become one of the controlling factors of route selection. Potential landslides, as the most common geological disasters on mountainous highway construction, for it is failed to take reasonable measures to avoid or control in route selection stage, often causing huge security hazard and economic loss in highway construction and operation stages. Combined with the experience of route selection in Baoshen highway, the basic principles of route selection in the potential landslides areas are summarized.
