【摘要】 随着国家的飞速发展和城市基础建设的不断进行,地下管道埋设工程越来越多,为保证顶管施工过程中的安全以及保护原场地地下管网,施工前有必要对顶管施工路径方向地下障碍物的走向位置和埋设深度进行详细勘探。物探技术利用先进的物探仪器来摄取地下物理场的分布并与均质条件下的物理场相比较,找出差异的部分来研究与勘探对象之间的关系,被广泛应用于解决地下工程问题。地质雷达与地震映像物探方法由于其具有省时、高效、能减少勘探工作量,降低勘探成本,提高地质勘探质量等优点已被很多工程实例所证实。通过天津市某顶管施工路径障碍物探测实例,分析地质雷达和地震映像方法在应用于顶管施工路径方向障碍物的探测工作中的有效性。更多还原

【Abstract】 With the rapid development and ongoing conducting of urban infrastructure,underground pipeline projects are getting more and more.In order to guarantee the safety and protect the original underground pipes in the process of pipe jacking construction,it is necessary to give a close exploration on the underground obstacles in the direction of pipe jacking construction path.Been widely used in solving underground construction problems,geophysical exploration technology uses advanced geophysical exploration equipments to ascertain the distribution of underground physical field,makes a comparison with the physical field under homogeneous conditions,and lastly finds out the differences to research on the relation with the exploration object.The object exploration methods of geological radar and seismic image have many advantages including time saving,high efficiency,reducing quantity of exploration work,lowering exploration cost,and improving geology exploration quality,which have been approved by many practical engineering cases.Through a practical case of obstacles exploration in pipe jacking construction path in Tianjin,this paper gives an analysis of the efficiency of methods of geological radar and seismic image in the application of obstacles exploration in the direction of pipe jacking construction path.更多还原
