通过对双向、四向土工格栅的拉伸试验,总结了格栅拉伸强度和延伸率变化规律,得出了不同类型土工格栅的破坏形式.试验表明:抗拉强度随着拉伸速率的增加而增大;双向格栅的延伸率随着拉伸速率的增加而减小,而四向格栅的延伸率变化不大.

Through the tensile test of two-way and four-way geogrid, this paper summed up the variation of grill tensile strength and eongation and obtained the destruction form of the different types of geogrid. The test showed that:tensile strength increases with increasing stretching rate;geogrid elongation decreases with increasing stretching rate, while little change in elongation of the four-way grille.
