TST超前地质预报在秘鲁圣加旺水电站TBM施工中的应用

Application of TST Advance Geological Prediction in TBM Construction of San Gaban Hydropower Station in Peru

地质问题导致的TBM卡机情况时有发生,一旦出现卡机,严重影响施工进度。因此,对于围岩状况的超前地质预判和提前应对处理十分必要。秘鲁圣加旺水电站项目采用TST超前地质预报技术对TBM施工段前方围岩状况进行预报,结合TST原理对预报结果进行解读,实际围岩状况与预报结果吻合度较好。

TBM stagnation caused by geological problems frequently happens,once it occurs,it greatly affects the construction progress.Therefore,it is necessary to pre-judgment and deal with the surrounding rock conditions in advance.The San Gaban hydropower station in Peru uses the TST tunnel geological prediction technology to forecast the surrounding rock conditions in front of the TBM construction section.Combining with the principle of TST technology to interpret the forecast results,the actual surrounding rock conditions are in good agreement with the forecast results.
