花岗岩残积土是一种特殊性土体，是混粒土的一种特殊类型，从而导致浅层地基承载力也具有特殊性。作者首先分析了现行实验评价方法的利弊关系，以大量的野外实验和室内实验资料为依据，确定了其它测试方法评价该类土体浅层地基承载力的可行性，并提出了利用标准贯入试验击数确定浅层地基承载力的修改方案。并探讨了土体含水量和浅层地基承载力和这些影响因素之间的相互关系。
Granite residual soil is a kind of special soil, which is a special type of mixed-grain soil, which leads to the special bearing capacity of shallow foundation. The author first analyzed the advantages and disadvantages of the current experimental evaluation methods. Based on a large number of field experiments and laboratory experiment data, the feasibility of other test methods to evaluate the bearing capacity of shallow soil foundations was determined, and the use of standards was proposed. Test number to determine the shallow ground bearing capacity of the modified program. The relationship between soil water content and bearing capacity of shallow foundation and these influencing factors was discussed.
