大型贯通测量管理技术实例与探讨

摘要

According to the specific conditions of gategateway through engineering in Yunxi 1360 platform central shaft,determines the allowable variation of coalescence,proposes two kinds of breakthrough measurement scheme. Through predicting the error of two kinds of schemes,and according to the error prediction deviation and coalescence allowable deviation,determines the breakthrough survey scheme.After the project completed,the actual coalescence deviation are determined in time,the selected scheme are verified,the basic principles and methods that should be followed in large breakthrough engineering surveying management are proposed.%根据云锡1360平台中央竖井平巷贯通工程的具体情况，确定了贯通允许偏差，提出了两种贯通测量方案。通过对两种方案进行误差预计，并根据误差预计偏差及贯通允许偏差值，确定了贯通测量方案。在工程贯通后，及时测定了实际贯通偏差值，并对所选择的方案进行了验证，提出了大型贯通工程测量管理应遵循的基本原则和方法。
