砂质

It is revealed from the analysis that the distribution, composition, lithofacies changes, and the formation mechanism and age of the relict sand are not consistent with the present depositional environment of this area.

它是在晚大理冰期最低海面后海平面不断上升过程中不同阶段的滨海相沉积，从冰后期海平面大规模上升以来，沉积作用在这些地区是微不足道的或者竟完全缺失，从而使砂质沉积直接裸露在海底表面，未被现代沉积所覆

In this paper, mechanical properties of the sandy silt and fine sand mixed with cement and fly ashes in different amounts after different ages curing are researched, and the effect of cementing is compared. Through pull-out tests and direct shearing tests of geogrid in various soil, the interface characteristics of between geogrid and soil are measured.
