该文主要介绍了TSP203的工作原理及其在上(海)—瑞(丽)高速公路某隧道施工中的具体应用情况。作者将TSP203的预测结果和最终开挖后的地质情况进行了详细的对比分析,说明预测结果基本正确。通过对预测结果的反馈对比分析获得一些经验教训,并提出一些新的见解,为今后的工作提供了有益的借鉴。 This paper mainly introduces the working principle of TSP203 and its application in the construction of a tunnel of Shanghai-Ruili Expressway. The author carried out a detailed comparative analysis of the prediction results of TSP203 and the geological conditions after the excavation, which shows that the prediction results are basically correct. Through the comparative analysis of the results of the forecasting, some lessons have been gained and some new ideas have been put forward, which provide useful references for future work.
