摘要
本文对两井定向联系测量方法在城市地下综合管廊工程中应用的可行性进行了分析研究。经实例验证,两井定向联系测量方法在城市地下综合管廊工程测量中的应用是可行的,且测量精度完全能够满足工程需求。该技术的引入可以改善传统联系测量方法,无论是测量作业效率,还是测量结果的精度都得到了很大的提高,具有广阔的应用前景。
The feasibility of the two-well directional contact survey method is analyzed in this paper. Through comparison test with the results of traditional directional contact survey method, it is proved feasible that the application of two-well contact survey in underground pipe gallery. The accuracy can meet the engineering requirement. The introduction of this technique can improve the traditional contact measurement method for long time occupancy of the shaft. The influence of the pitch error on the measurement accuracy is greatly reduced due to the increase of distance between the two steel wires.
