摘要
提出了岩土工程领域土拱理论中几个值得探讨的问题 ,如拱脚的存在形式、拱形、拱体几何参数及微观特性等 .根据土拱的不同形成机制 ,指出拱脚的存在形式有直接拱脚、摩擦拱脚、土体拱脚及二异拱脚 4种 .在此基础上 ,通过工程实例对拱形及拱体几何参数提出了初步见解 。
Some issues in the theory of soil arch in the geotechnical engineering are broug ht forward, including the forms of spandrel, the shape, geometric parameters and microscopic properties of soil arches etc . From the forming mechanism of s oil arches, they are divided into four types, i.e. directly-forming spandre l, induced-friction spandrel, solum-forming spandrel and spandrel with differe nt bases. Based on an engineering instance, some primary views on the geometric parameters of arch shape and arch body are put forward to develop and perfect th e theory of soil arch.
