Abstract

There is high requirement to the foundation of the raceway of container gantry crane. However, the marine soft soil is distributed extensively at ports. How to predict and control its settlement is a key to assure the design safety of container gantry crane. In the paper, the settlement and bearing capacity of natural and composite foundation of raceway of container gantry crane under design load is analyzed by finite element method of on the basis of geological data, foundation treatment. The relationship of different deformation modulus and foundation bearing capacity is obtained by considering the strength of foundation and the requirement of settlement. The characteristic value of bearing capacity is 150 k Pa, when the settle of ground arrives at 30 cm. Now the inclination value of the container gantry crane is 0.17%, it is less than the permitting value of laws. The boundary of basis is easy to failure, the treatment range extension of foundation should be considered.
