摘要
研究多元复合地基承载力对其设计具有重要意义.从多元复合地基受力条件出发,研究了强度发挥系数和承载力修正系数对多元复合地基承载力的影响,阐述了多元复合地基承载力确定的2种方法,即试验法和分析与经验相结合的方法.对于试验法,多元复合地基承载力确定关键在于强度发挥系数和承载力修正系数的确定;而对于分析与经验相结合的方法,则给出了强度发挥系数和承载力修正系数的经验值.
The foundation researching the capacity of multi-element composite foundation is very importment for designing. The influence of capacity intensity exert coefficient and capacity correct coefficient for the capacity based on the force balance is discussed. Two methods of confirming the capacity of multi-element composite foundation is expounded i.e. the test combining with experience. For the test method, the keypoint is the confirming of capacity intensity exert coefficient and capacity correct coefficient;For the another, the experience value of intensity exert coefficient and capacity correct coefficient is given out.
