　　Hangzhou Xiaoshan International Airport The landside transportation center foundation pit has a plan area of about 100,000 square meters and an overall excavation depth of 18.6 meters. The eastern part adopts the semi-top-down method. As a key project of the Hangzhou Asian Games with a tight schedule, it needs to consider the mutual influence with the T4 terminal under construction on the west side, the subway station under construction on the north side, and the high-speed railway station under construction on the south side, so as to ensure that the T1 terminal on the east side remains "non-stop flight and non-stop operation".

　　Hangzhou International Financial Center Project (Jianghehui Urban Complex) The foundation pit has a plan area of about 200,000 square meters and an overall excavation depth of about 18 meters. Due to development reasons, it has been excavated in multiple phases. It is necessary to consider the impact on the shield tunnels of Hangzhou Metro Line 6, the shield tunnels of Hangzhou Metro Line 9, the large-diameter third sewage main pipe, and the large-diameter shield tunnel of the Zhijiang Canal, while also preventing groundwater seepage caused by the adjacent Qiantang River and the Beijing-Hangzhou Grand Canal.

　　Hangzhou West Railway Station Station-City Complex Project The foundation pit has a plan area of about 120,000 square meters and an overall excavation depth of more than 23 meters. It is connected with the high-speed railway station building under construction and 4 subway stations. The site elevation is complex, the surrounding environment is constantly changing, the construction conditions are limited, and the schedule is tight. The pit bottom is close to a confined aquifer with a high water head.
