<p><em>Pile foundation is one of the solutions of high-rise buildings not in the area of restrict area. When the pile foundation reached until the hard ground reaches, a small settlement is expected and  different  setlement  are  not occur. The objective: analyze the results of loading tests compared carryng capacity calculations, pile cap thick required secure.</em></p><p><em>The research method used in this research is the case study of pile foundation  twelve floors building in Batam island. The reaction on the pile is analyzed using software program of non-linear structure version 9.5 which is supported by primary data, namely loading test and secondary data of soil investigation and the largest column force taken on the pole 1.618,854 ton, Mx -7,936 ton meter, My -75,531 ton meter.</em></p><p><em>Carrying capacity analysis is based on friction and end bearing and calculated pole efficiency. The axial load of the plan is supported by 16 (sixteen) piles, based on the loading test (P) the ultimate pile foundation reaches 200% (two hundred percent) in the amount of 411.52 tons. </em><em>Single pile carrying capacity is 205.76 tons .Settlement in the loading test results 10mm is smaller than from the setlement in calculation results. The stress acting on the pile cap of 12.453 kg/cm<sup>2</sup> is smaller than the permit strees of 13 kg/cm<sup>2</sup>.</em></p>

This paper analyzes the propagation characteristics of stress wave in the cap-pile system. Based on reflected wave method, the propagation velocity-time curve of stress wave in the defective pile with cap is calculated theoretically. Then the calculation result shows that the waveform curve by theoretical analysis is consistent with the defect location and pile position, and the waveform curve well reflects the propagation characteristics of waves in the pipe with cap. Finally the theoretical analysis method is used to assist the field testing, and compared with the test result to describe the integrity status of pile.

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.

With development of modern science and technology, pile type and pile foundation type, construction technology and construction equipment, pile foundation theory and design method have large evolution. Pile foundation has been to the ordinary foundation type used in the field with week soil texture for constructing all kinds of buildings, especially for high-rise building, heavy duty factory and the structure with special requirement.
