摘要
红层是我国南方分布广泛的白垩纪沉积软岩,大量试验数据分析表明,反映红层工程性质的一些重要物理力学指标间存在着较好的相关性,由于岩石结构的差异,不同地区红层的相关方程差异较大。通过对试验数据进行回归分析,建立了抚州市区红层的饱和重度与饱和单轴抗压强度、饱和单轴抗压强度与割性模量、三轴抗压强度与围压之间的相关方程,分析了现有点荷载试验强度与饱和单轴抗压强度相关方程对抚州红层的不适用性,并建立了相应的相关性明显的相关方程。
Red beds,which is Cretaceous soft rock,distributes extensively in the south of China.Data of test indicates that there are regression equations among major physical physical and mechanical indexes.Because of the different structure,the equations of regression of different areas are not the same.On the base of data from laboratory tests and in situ testing,equations of regression between.saturated uniaxial compressive strength and saturated unit weight,saturated uniaxial compressive strength and modulus of secant,triaxial compressive strength and confinement pressure.The unfitting of presenting regression equations between point olading strength and saturated uniaxial compressive strength had been analyzed and the fittings had been established for red beds in Fuahou.
