摘要
针对长沙市“红层”中极软岩石的物理力学特性以及岩样单轴抗压强度偏低导致评价岩石地基承载力偏低的问题进行分析,提出了用标准贯入和动力触探手段确定岩石地基承载力的可行性,并结合工程实例作了说明。
The problem of lower bearing capacity of rock foundation, caused by lower compressive strength of single axis of rock samples, and the physical mechanics traits of very soft rocks in Changsha ' Red Beds', was analyzed in the article. The feasibility of standard piercing and dynamical touch-survey methods determining the bearing capacity of rock foundation was put forward, and illuminated through engineering examples.
