Abstract

The vertical ultimate bearing capacity of a single pile is an important parameter required in the design of pile foundation. The vertical compressive static load test of a single pile is the most reliable method to determine the vertical ultimate bearing capacity of a single pile. However, the load test cost is high and the cycle is long. In the early stage of small and medium-sized projects or large-scale projects, the conditions for carrying out the vertical compressive static load test of a single pile are generally not available. Based on the geotechnical engineering of a coal-fired power station in Southeast Asia, the vertical ultimate bearing capacity of a single pile is estimated by using the results of cone penetration test (CPT) and standard penetration test (SPT), and the ultimate bearing capacity is tested by high strain dynamic test. Compare various estimating value and high strain dynamic testing value to static load test value with ultimate vertical bearing capacity of a single pile, and then obtain the reliability of vertical ultimate bearing capacity of a single pile by means of CPT and SPT in this area. By means of the research results of this paper, obtain the vertical ultimate bearing capacity of PHC pipe pile quickly and accurately in this area for similar engineering design. Ultimately achieving the goal of shortening the construction period and reducing geotechnical investigation cost.
