Pile Foundation Analysis on High – Rise Building using Finite Element-Spring Method on Sandy Clay Soil

This article reports a sub-domain method to analyze the dynamic interaction of soil-high-rise building group considering sit effect, which is the extension of the domain reduction method proposed by Bielak and his coworkers in the framework of the finite-element method, originally for building–soil–foundation interaction problems. The whole domain with high-rise building group is divided into two interrelated sub-domains, the external domain and the internal one. And the method contains two steps. In addition, the effect of the external domain to the internal domain is expressed by the equivalent forces which are put on the nodes of the interface between the two sub-domains in the second step. The formation of the equivalent force is attained according to the equation of motion. In the first step the free-field ground motion is calculated under the bedrock wave excitation, and all the nodal displacements are stored. Then the equivalent forces are calculated according the data in the first step, using the formulation of the equivalent force. In the second step a finite element analysis model of the sub-domain containing the internal domain and the high-rise building group is established, and the equivalent forces are put on the nodes of the interface. Later the seismic response of soil-high-rise building group can be calculated.

Building Project

As the population growth and land resources declining, high-rise building project is increasingly common in the construction work. Through in-depth thinking and active exploration, specific attention to matters of deep foundation pit and pile foundation construction technique, which is the key construction techniques in the high-rise building project, was summarized in this article. It suggests to make a careful and detailed geological survey, and then choose the right design program and develop a reliable construction plans. This scheme was proved to be a useful reference and guidance for the development of high-rise building construction technology.

Complex Building

Problematic issues of construction of pile-foundation slab of high-rise residential building in the area of underground mining (underground mining with general under working area 25%; the fissured limestone may collapse under the weight of the building) are systematized. The experience of modeling by method of ultimate elements of pile-foundation slab of three-section residential building in the area of underground mining and results of the geodesic monitoring of complex building are presented.
