摘　　要：为提高地下管廊验收控制测量的精度,该文针对地下管廊出入口狭小的特点,提出短边导线+陀螺定向组合方法进行联系测量。该方法采用新型三架仪器法提高短边导线测角精度,按照单一导线理论推算地下管廊控制测量的技术要求,构建了地下管廊验收控制测量技术,并在实际应用中取得了良好的效果,对类似工程具有一定的借鉴作用。In order to improve the accuracy of acceptance control survey of underground pipe gallery, aiming at the characteristics of narrow entrance of underground pipe gallery, the short-side traverse + gyrostatic orientation survey combination method is proposed for the connection survey. And the new trigeminy tytripod method is adopted to improve the angle measuring accuracy of short-side traverse. According to the theory of single traverse, the technical requirements of control survey for underground pipe gallery are deduced, and the control survey technology of underground pipe gallery is constructed. The method achieves good results in practical application and has certain reference for similar projects.
