Application of Self-Balanced Method Static Load Test of Super Long and Large Diameter Pile Foundation in Beibu Gulf Area
This article focuses on the detection method of the ultimate vertical compressive bearing capacity of super long and large-diameter pile foundations,using the Xicun Port Cross-Sea Bridge project in Beihai City as a reference.The study selects the equilibrium method static load test as the research object and explores the feasibility of applying this method in pile foundation engineering in the Beibu Gulf area.By selecting key parameters such as the testing system and the position of the load box installation,as well as analyzing the corresponding relationship between the load and the upward and downward displacement during the loading process,the load-displacement(Q-s)curve and displacement-time logarithmic(s-lgt)curve are plotted,and the curve characteristics are analyzed.The results show that the characteristic values of the vertical compressive bearing capacity of the three test piles in this project all meet the design requirements.These research findings provide valuable experience for the construction of similar projects in the Beibu Gulf area.
