The open TBM bores through limestone section of 7 km long of Bid Section No. 4 of Songhua River Water Conveyance Project. The advanced geological prediction system and lining system of TBM are designed based on characteristics, i.e. long distance, large crosssection, rapid boring and strengthened support of the project. And then, corresponding construction technologies and countermeasures are decided for bad geological conditions. The TBM has successfully bored through the limestone section; the construction cost has been reduced and the construction schedule has been shortened by relevant design, construction technologies and countermeasures adopted.
