| Abstract: | Based on the field data of the seasonally frozen ground during 1985-1986, the authors mainly discuss the developing characteristics of seasonally frozen ground, analyse the factors and laws influencing on the development of the seasonally frozen ground in the region of Yumenzhen, Gansu. Meanwhile, the authors put forward the frost heaving classification which is suitable for natural frozen ground conditions in this region. In addition, the division and evaluation of natural frost heaving are also proposed.
The research indicates that the reginal climatic conditions control the general laws and features of the formation development and disappearence of the seasonally frozen ground. Geomorphic unit is the most important factor resulting in the difference of the seasonally frozen ground. The buried depth of ground water is the difinitive factor leading to differentiation of the seasonally frozen ground in fine-grained soil plane and human activity has a great influence on frozen condition.
According to geomorphic unit and buried depth of ground water, seasonally frozen ground in this region can be corresponding divided into 4 seasonally frozen ground areas and 4 frost heaving types, they are unfrost heaving, weak frost heaving, frost heaving and strong frost heaving. |
