摘要
结合大型土石坝工程的设计与施工控制,应用级配模拟外推法和基底物理模型校正法,对大粒径无粘性粗粒土极限密度(最大、最小密度)的模型规律进行了系统的试验研究,提出了可供实用的计算模式和一整套技术程序。为60年前太沙基提出的控制沙土压实的相对密度理论在该领域的开拓应用,提供了新的科学依据,填补了近50年来该领域的空白。
Combined with the design and construction control of the large earth-rock dam, and applying the extrapolation method for simulating the particle size distribution and the correction method of the fundational physical model, the model regularity of limiting density（maximal, minimal density） for the coarse grained soil cohesionless with great partide size have been Carried out system test research, also have put forward the practical calculating modality and a set of the technical regulations, for application of the theory of relative density into practical provide the new scientific basis and filled the gaps of this field.
