Abstract

The paper demonstrates the possibility of determining of the elastic parameters of a railway roadbed from the results of seismic observations of vibrations generated by a passing train. The rationale for the monitoring method is obtained by analyzing our own experimental data and theoretical calculations with good agreement between theory and experiment. As the method part, we considered the requirements for seismic equipment and indicated the most suitable types (Trillium Compact-120s is the best), which can be located near the roadbed at a safe distance from it. Such a sensor with a suitable data logger and seismic data processing program can be included in the set of methods for state railway roadbed monitoring. These assessments of the resolution of the proposed method show that it is sufficiently sensitive to detect the deformation of soil properties at the early degradation stage, which is especially important for permafrost soils.

用地震观测法确定铁路路基的原位弹性

摘要

本文证明了根据对过往列车产生的振动进行地震观测的结果来确定铁路路基弹性参数的可能性。通过分析我们自己的实验数据和理论计算得出监测方法的原理，理论与实验之间具有良好的一致性。作为方法的一部分，我们考虑了对地震设备的要求，并指出了最合适的类型（Trillium Compact-120s是最好的类型），可以将其放置在路基附近并且与路基保持安全距离。具有合适的数据记录器和地震数据处理程序的这种传感器可以被包括在用于国家铁路路基监视的方法集中。
