岩土的概念是一个结合体,就是在地面的土层中的任何的岩石和土的混合物。而在岩土中含有比较特殊的物质的时候,或者是岩土的内部结构以及物理学性质等要素有异于其他的普通的岩土,这种比较特殊的性质就是特殊地质性质。在特殊岩土中,有些会很容易就导致施工地发生地质灾害。这些比较具有破坏性的特殊岩土有软土、冻土、红黏土以及黄土和泥炭土等特殊的岩土类型。在实际的施工之前就要对实际的作业地点的岩土的性质等进行详细的工程勘察,以为后续的施工做好准备。
The concept of geomagnetism is a combination of any rock and soil mixture in the earth’s surface layer. When the soil contains more special materials, or the geotechnical internal structure and physical properties and other factors are different from other ordinary geotechnical, this more particular nature is the special geological properties. In special geotechnical areas, some of them can easily lead to geological disasters in the construction site. These more destructive special rocks include soft soil, frozen soil, red clay, and special types of rock such as loess and peat soil. Before the actual construction, it is necessary to carry out detailed engineering investigation on the nature of the geotechnical work at the actual work site so as to prepare for the subsequent construction.
