桩基是目前广泛采用的一种基础形式。在桩基设计中,准确地确定单桩承载力是至关重要的。常用的确定单桩承载力的方法很多,但仍以桩静载荷试验方法较为可靠。载荷试验方法由于受设备、成本以及时间等条件限制,试验数量有限,不能从概率取值的角度来全面了解桩承载力值的总体分布和进行可靠度设计。静力触深在机理上与桩有较多相似之处,在确定单桩承载力方面,它是最理想的经验方法之一。
Pile foundation is a basic form widely used at present. In pile foundation design, it is very important to accurately determine the bearing capacity of a single pile. There are many methods used to determine the bearing capacity of a single pile, but the pile static load test method is still more reliable. The load test method is limited by the conditions of equipment, cost, and time, and the number of tests is limited. Therefore, the overall distribution of the bearing capacity value of the pile and the reliability design cannot be fully understood from the viewpoint of probability value. The static contact depth has more similarities with the pile in the mechanism, and it is one of the most ideal empirical methods in determining the bearing capacity of a single pile.
