陇西地区公路沿线人工洞穴及采空区等下伏不良地质体分布广泛 ,严重影响公路的施工、运营安全和工程建设的规模及投资效益。下伏洞穴及采空区具有隐伏性强、空间分布规律性差、冒落塌陷无法预测等特点。洞穴采空区处治的措施应根据其与公路的空间位置关系、规模大小、稳定状态、填充情况、周围环境等因素 ,经综合技术经济比较后综合确定 ,并积极探索应用新技术、新方法和新工艺。 The distribution of unfavorable geologic bodies such as artificial caves and goafs along the highway in Longxi area is widespread, seriously affecting the construction and operation safety of roads and the scale and investment benefits of construction. Underlying caves and goafs have the characteristics of being invisible, poorly distributed in space, unpredictable and so on. Measures for treatment of mined-out areas of caves shall be determined comprehensively after comprehensive technical and economical comparison according to the spatial position of the highway, size, steady state, filling conditions, surrounding environment and other factors, and actively explore the application of new technologies and new methods New Technology.
