摘　　要：沈阳城区埋藏有较大厚度的上更新统Q_3期中粗砂、砾砂和圆砾层,分布稳定,承载能力也较高,高层建筑物常以其为地基持力层,但目前仍未对其承载能力达到较充分的使用。通过几个典型工程的测试和试验,挖掘沈阳城区深层砂土、碎石土的承载能力的潜力,给出其承载力特征值和变形模量的可用范围,为合理利用良好天然地基资源提供了依据,并提出进一步研究的方向。There buried rather thick upper Pleistocene series Q3 stratum in Shenyang area, including medium, coarse sand, gravel sand and round gravel, these stratums have stable distribution and biggish bearing capacity to be the foundation bearing stratum of high-rise structure, but not yet to use the bearing capacity more fully. This paper exploit the bearing capacity of sand and gravel in Shenyang through test and experiment of several typical projects, and give the available range of the bearing capacity characteristic number and deformation modulus, providing a basis for the rational utilization of good natural foundation, at the same time, proposes the research direction in future.
