使用非常规的探地雷达高新技术对北京市平安大街、东四环路、朝阳路、王府井大街及东方广场等项市政工程道路地下污、雨水顶管及电力、热力暗挖隧道的顶部围土状态进行了探测检测。将发现的国土扰动异常划分为微扰动、中度扰动、重度扰动、土质疏松及空隙、空洞等异常,并给出详细参数,为注浆加固提供具体部位,为市政建设道路地下优质施工提供了新的探测检测方法。 Using unconventional ground-penetrating radar high and new technologies, the top and bottom of tunnels for underground municipal sewage, rainwater pipe jacking and power tunnels in Beijing’s Fourth Avenue, East Fourth Ring Road, Chaoyang Road, Wangfujing Street and Oriental Plaza Soil conditions were detected. The disturbances of the national disturbance discovered in this paper are divided into three types: anomalies such as slight disturbances, moderate disturbances, severe disturbances, loose soil, voids and voids, and detailed parameters are given to provide specific sites for grouting and reinforcement, which provides a good site for underground construction of municipal roads New detection detection method.
