Construction method for supporting pile of deep foundation pit of pipe gallery underneath passing existing operating railway
The invention relates to the technical field of deep foundation pit supporting construction, in particular to a construction method of a deep foundation pit supporting pile of a pipe gallery underneath passing through an existing operating railway, which comprises the following steps of: performing correlation analysis on sensitive data such as supporting structure parameters, rock-soil body parameters and rainfall parameters which influence the protection stability of railway pier columns; according to the method, the intensity of various sensitive factors influencing foundation pit support deformation is determined, various sensitive data are effectively restored by introducing a linear interpolation method, the incidence relation between the sensitive factors and the construction process is qualitatively analyzed, and finally, the protection characteristics of the railway pier column are well tracked and predicted by applying a radial basis function neural network tracking model. And finally, according to feature classification, the construction method of the pipe gallery deep foundation pit supporting pile underneath passing through the existing operating railway is provided, the method can reduce construction accidents, and the method is convenient, fast, safe and efficient.
本发明涉及深基坑支护施工技术领域，具体为一种下穿既有运营铁路的管廊深基坑支护桩施工方法，对影响铁路桥墩柱防护稳定的支护结构参数、岩土体参数、降水参数等敏感性数据进行关联度分析，以确定影响基坑支护变形的各类敏感性因素强弱，通过引入线性插值方法有效修复了各类敏感性数据，定性地分析各敏感性因素与施工过程的关联关系，最后运用径向基函数神经网络跟踪模型较好地跟踪并预测了铁路桥墩柱防护特征，最后根据特征分类提出一种下穿既有运营铁路的管廊深基坑支护桩施工方法，该种方法能够减少施工事故的发生，方便快捷，也安全高效。
