| 摘 要： | 碎石土除了具备一般意义上土的性质外,还有自身的一些性质.通过对碎石土进行天然状态及饱水状态下的载荷试验结果进行分析,将实测值与弹性理论计算值相结合,根据结果对碎石土的一些性质进行预估,发现利用弹性理论能较好地符合碎石土的受力变形性能,并通过其他常规试验(如物质组成等)可以分析碎石土的基本结构以及受力变形性能.

| Abstract: | Gravelly soil has its own special character besides some common characteristics. Based on the studying of test data about the foundation load in the original state and saturated state and by comparing the practice value with the theoretic value of elasticity, we predicted the special character of gravelly soil and found that the elasticity theory can be in good accord with the practical pressure-distortion capacity of the gravelly soil, and the structure and pressure-deformation capability can be studied with other tests (such as substance composing). |
