川藏公路横穿我国西部两大地貌单元及其过渡地带,其间所遇的一些坡体病害具高寒冷、高海拔的环境特色和规模巨大、性质复杂的特点,而且常常多位一体,成群出现.这些组合的坡体病害,不仅不能用其中任何一种来反映发育特征,而且其发展也同其他事物一样经历着从发育、成长到灭亡,循环往复的演变过程.从代表性坡体病害——川藏公路二郎山1号坡体病害的机理分析出发分别通过地质力学模型试验、数值计算、立体原位测试等多种手段模拟、研究并通过实际工程结构调控了这一大型坡体病害发育末期的演变.从中得知,这类坡体病害具备更优势的地质背景和条件;不同病害形式间的作用比单一影响因素的作用更可怕;除绕避方案外,只有用结构与病害体协调作用的综合先进方法才是治愈该类病害的有效手段.
Sichuan-Tibet Highway crosses the two major geomorphic units and their transitional zones in the western part of China. During this period, some of the slope diseases encountered are characterized by high cold and high altitude, large scale and complex nature, and are often integrated with one another in groups Appear.The combination of slope disease not only can not use any of them to reflect the developmental characteristics, but also its development, like other things, goes through the process of evolution, growth, extinction and circulation.From the representative slope disease - Sichuan-Tibet Highway Erlangshan No. 1 slope disease mechanism analysis starting from the geomechanical model tests, numerical calculations, three-dimensional in situ test and other means to simulate and study and through the actual structure of the project to regulate the large slope diseases The development of the end of the evolution from which we know that this kind of slope diseases have more superior geological background and conditions; the role of different disease forms than the single influencing factor is more terrible; except to avoid the program, only with the structure and disease body An integrated and advanced method of coordination is an effective means of healing such diseases.
