| 摘 要： | 系统地分析了现阶段公路和水利工程建设中经常遇到的土石混合料路基的压实问题、力学特性等。通过理论分析，提出了应用剪切波速评价土石混填路基孔隙率的新方法，并开展了孔隙率～单位比能相关试验，研究了不同含石量孔隙率不再变化时的单位比能，提出以孔隙率为压实质量指标的控制标准，为应用剪切波速检测土石路基压实质量提供了理论依据。

| Abstract: | The problem from compaction and the mechanical properties etc. of the soil-stone embankment frequently used in constructions of both the high way and water project are systematically studied herein. Based on the theoretical analysis, a new method to evaluate the porosity of the embankment by shear wave velocity is proposed and then the tests related to the correlation between the porosity and unit specific energy are introduced, during which the unit specific energy of the embankment with different stone content under constant porosity is studied. Furthermore, a porosity-based compaction standard for the quality control is put forward, which provides an important theoretical basis for detecting the compaction quality of the embankment concerned with the shear wave velocity. |
