摘要
传统竣工测量成果在表达方式上存在不直观和判读性差等问题,不能满足综合管廊后期运维管理的要求。本文提出基于三维激光扫描技术的架空式综合管廊沉降监测方法,应用激光扫描技术获取架空式综合管廊的实时沉降监测值,并借助脉冲测距法、激光三角法及脉冲相位法弥补外界干扰因素对监测稳定性造成的影响;采用架空式综合管廊沉降数据监测技术精确获取沉降数据,并基于非线性有限元模型与形态分析方法分析综合管廊内部沉降数据;最后通过实际案例验证基于激光扫描技术的架空式综合管廊沉降监测方法的有效性。结果表明,三维激光扫描技术的沉降监测方法可以准确得到架空式综合管廊的沉降情况。
The expression mode of traditional as-built measurement results are unintuitive and poorly interpretable, which can no longer meet the requirements of post-operation and maintenance management of integrated pipe gallery. Therefore, a settlement monitoring method of overhead integrated pipe gallery based on 3D laser scanning technology is proposed in this paper. This method uses the laser scanning technology to obtain the real-time settlement monitoring value of overhead integrated pipe gallery, makes up for the influence of external interference factors on its monitoring stability with the help of the pulse ranging method, laser triangulation method and pulse phase method, uses a monitoring technology for settlement data of overhead integrated pipe gallery to accurately obtain settlement data, and analyzes the internal settlement data of the integrated pipe gallery based on the nonlinear finite element model and the morphological analysis method. Finally, this paper verifies the effectiveness of the settlement monitoring method of the overhead integrated pipe gallery based on the laser scanning technology through a practical case. The results show that the settlement monitoring method of 3D laser scanning technology can accurately obtain the settlement of the overhead integrated pipe gallery.
