摘　　要：通过现场试验路堤和室内模型试验研究了几种较有代表性的软岩填石料的长期沉降变形特性,证明了软岩填石料的长期变形性能除了与填石料的岩石特性和压实密度有关外,风化程度、干湿循环是影响填石料的长期变形性能的主要因素。The research on long term settlement deformation characteristics of kinds of representative soft rock filling materials for high speed railway embankment with site test, indoor test, model test is introduced. The tests show that except its characteristics and compaction density of soft rock-fill materials, weathering and wet-dry circulation are the major influence factors for long term settlement deformation behaviour of the materials.
