摘要
铁路建设项目受地质灾害影响很大，在项目建设前进行地质灾害危险性评估就显得非常重要。在评估过程中，只有对灾害类型、规模、影响范围、稳定性、危险性和危害程度作出准确的评估，其结论才能成为以后拟建项目后续工作的科学依据。文章以一改建铁路项目为例，探讨了突发性地质灾害和缓变地质灾害危险性评估的定性、半定量评价方法，并根据评估结果，提出了相应的防治措施。
Geological hazard has huge influence on railway construction project, so it is very important to carry out geological hazard evaluation before project construction. During evaluation, only exact evaluation of hazard type, scale, influence range, stability, risk and harmful extent can ensure its conclusion becoming the scien- tific basis for the follow-up work of the project to be built. This paper discusses the qualitative and semi quantitative evaluation method for unexpected geological hazard and gradually transitive geological hazard based on a railway project and puts forward the corresponding countermeasures according to the result.
