Abstract

This study introduces a cloud-native framework that alleviates the intricate workflows, limited real-time performance, and heavy software dependency inherent in conventional tunnel-support analyses. A purely data-driven surrogate, trained on 4,933 heterogeneous tunnel sections, replaces time-consuming finite-difference simulations. Latin-hypercube sampling was used to populate the design space and to train a single full-section model that jointly predicts all stability indices. Displacement errors typically fall between 1.3 mm and 2.1 mm, with safety-factor errors around 0.11, while inference is approximately 100 times faster than finite-difference solutions. A lightweight blocking multi-thread HTTP service encapsulates the model, delivering real-time support-design feedback via standard web browsers. The proposed approach lowers the technical threshold of tunnel-support analysis and provides an efficient, real-time numerical computing solution for tunnelling in complex geological conditions.

云数值计算：利用数据驱动的数值模拟和阻塞子线程HTTP协议对铁路隧道进行信息支持计算

本研究引入了一个云原生框架，该框架减轻了传统隧道支持分析中固有的复杂工作流程、有限的实时性能和严重的软件依赖。一个纯数据驱动的代理，在4933个不同的隧道截面上进行训练，取代了耗时的有限差分模拟。拉丁-超立方体采样用于填充设计空间，并训练单个全截面模型，该模型联合预测所有稳定性指标。位移误差通常在1.3 mm到2.1 mm之间，安全系数误差约为0.11，而推断速度大约是有限差分解决方案的100倍。一个轻量级的阻塞多线程HTTP服务封装了这个模型，通过标准的web浏览器提供实时的支持设计反馈。该方法降低了隧道支护分析的技术门槛，为复杂地质条件下的隧道掘进提供了一种高效、实时的数值计算解决方案。
