Abstract: It has a practical importance for the systematic research on the design approaches of the punching and pressing machine foundations due their large earth work quantity, high equipment and installation cost and high requirements on the very small differential settlement as well as the restrictive installation alignment tolerance. This paper presents a case history of design of a heavy punching and pressing machine foundation in Guangzhou. The design details of the machine foundations and ground treatment of the heavy foundation are introduced and the approaches of determining the thickness of the side wall and the bottom slab of the foundation pit are demonstrated. The stress in the side walls are estimated using a special software. The subsurface conditions and the equipment requirement indicated that the prefabricated prestressed reinforced concrete pipe piles are used to support the machine foundation.
