Real-time early warning method for collapse disaster risk in pipe pulling crossing road construction
The invention provides a real-time early-warning method for collapse disaster risks in construction of crossing a road through a stay pipe, and the method comprises the steps: building a finite difference numerical model to simulate a stay pipe construction process based on physical and mechanical indexes of a construction site given in a geological exploration report and FLAC3D software, and designing a scheme through a multi-factor orthogonal design method, thereby achieving the real-time early-warning of the collapse disaster risks in the construction of crossing the road through the stay pipe. And sequentially importing into a numerical model for forward analysis to obtain multiple groups of different site soil mass mechanical parameters and deformation calculation values of corresponding road surface monitoring points. And taking the calculated value as a learning sample set and a test sample, and obtaining a trained least square support vector machine model through MATLAB. The method has the beneficial effects that compared with a conventional stability evaluation means, the numerical model is continuously corrected and adjusted in combination with real-time deformation data, and the next road surface deformation is predicted in advance. According to the invention, real-time dynamic advanced early warning of pavement deformation in the pipe drawing construction process can be realized. Risk management and control and fine management of site construction are facilitated, and major safety accidents are avoided.
本发明提供了一种拉管穿越道路施工塌陷灾害风险实时预警方法，发明基于地勘报告中给出的施工场地物理力学指标，FLAC3D软件建立有限差分数值模型模拟拉管施工过程，并通过多因素正交设计方法设计方案，依次导入到数值模型中做正向分析，得出多组不同场地土体力学参数与对应路面监测点的变形计算值。将计算值作为学习样本集与测试样本，通过MATLAB获得训练后的最小二乘支持向量机模型。本发明有益效果：本方法与常规稳定性评价手段相比，做到结合实时的变形数据不断对数值模型进行修正、调整，并提前对下一步路面变形进行预测。本发明可实现拉管施工过程路面变形实时动态超前预警。有利于现场施工的风险管控与精细化管理，避免重大安全事故的产生。
