Abstract：The CK570C section of Xingchung line is the most difficult construction project in the history of Taipei metropolis rapid transit system. This project goes from O8 station to O5 station. The total length of is 3.2 km and this section includes 3 stations. Of them，Taipei Bridge station (O7 station) is a side platform station and Cailiao station (O6 station) and Sanchong station (O5 station) are economic-style stations. In addition，there are two open-cut tunnels for rail section and cross-over section respectively，and four shield tunnels in the CK570C section. In this section，there are two difficult construction areas：one is cross-over structure for track turnout under the deep zone of Danshui River，and the other is Taipei Bridge station. From the consideration of construction，cofferdams are need before the construction of diaphragm wall. But the protection of river must be enhanced because the cofferdam may cause scouring to the bank and river bed.
