摘要
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。
Residual soil on granite is one of symmict soils, with its specific characteristics which results in a particular foundation loading capacity. From a large amount of field and indoor experimental data, the feasibility of other measuring methods for assessing foundation loading capacity was determined , and a revised scheme of determining shallow foundation loading capacity by SPT method is suggested by the author in the paper. The relationship between water content in soil, shallow foundation loading capacity and the affecting factors is discussed.
