锤击数对轻量土性能的影响分析

Effect Analysis of the Properties of Hammer Number on Light - Weight Soil

轻量土是一种新型的岩土工程材料，国内外关于锤击数对轻量土性能影响的研究尚无报道。为了研究锤击数对轻量土强度及密度的影响，试验分别选用15击、30击、45击、60击及75击作为试验的锤击数，并分别测定在不同锤击数下轻量土的强度及密度。试验结果表明，轻量土的密度及强度随着锤击数的增加而增大，因此，合理地选择轻量土试验锤击数对于试验结果相当重要。

Light - weight soil is a new type of geotechnical engineering materials. Studies on hammer number of light- weight soil was lack of reporting. In order to study hammer number influence on strength and density of light - weight soil, hummer number of 15, 30, 45, 60 and 75 were selected. According to different hammer number, strength and density of light - weight soil were measured. The results show that on the same condition strength and density of light - weigh soil increases with the increase of hummer number.
