The underground car park of Central Square of Yitian Village of Shenzhen City, constructed by central island method, is one of the biggest underground car parks and its structure is constructed by waterpumping and floatingresistant method. The comprehensive construction technologies of the car park are presented. The key construction technologies of central island method and cutandcover method of the car park and the waterpumping and floatingresistant method of the structure are proposed. The construction scheme is shortened, the cost is reduced, the construction materials are reused and the underground water is circularly used by using the construction technologies adopted.
