城市道路与地下工程综合测量方法

Surveying method for city highway and underground engineering

综合采用井上、井下导线测量和高程水准测量方法,结合隧道断面测量和地质雷达探测结果,对某城市次干道与主干道相交处西南侧电缆隧道及隧道外电缆线进行测量,并综合测量结果,确定了该次干道原设计匝道与主干道下方电缆隧道及其附属设施的具体位置和顶板标高,以及110 kV电缆的平面位置、标高和与隧道的连接位置,获取了修改原设计方案的资料.

Combined the methods of the ground and underground traverse survey with elevation leveling survey, and considering the result of tunnel section survey and detection of ground penetrating radar, the southwest side cable tunnel and cable conductors outside the tunnel on the crossing of main arterial highway and subordinate highway in the city were surveyed, and the surveying result was obtained. All the results show that location of the original design ramp of subordinate highway, the location of cable tunnel and accessory underground main arterial highway, and the elevation of top board, plane location and elevation of 110 kV cable, and linking place with the tunnelbe asswred be assured, materials to amend the original design project be obtained.
