摘    要:为加固土性软弱和有水的不良作用的土体而研制了新型土工布;它除兼有针刺无纺土工布和编织土工布的优点外,还具有一系列新的良好工程特性,这使它用在加固软土地基时的效果比较好.结合海堤地基加固工程的有限元对比计算也证明此点.初步探讨了与受力状况有关的疲劳损伤对它的抗拉强度的影响.利用图象处理成果计算得到了它的孔隙分形维数.

关 键 词:加固  软土  土工布  分形维数  疲劳损伤  有限元法

Abstract:The new developed geotextile for stabilization of soft and water content soil mass, not only has both the advantages of nonwoven needle geotextile and woven geotextile,but also has a series of new good engineering characteristics. These characteristics have good effect on strengthening of foundations on soft soil. And the effect is proved through FE analysis of coastal levee foundation stabilization. The fatigue damage affecting the tensile strength related to force conditions is also discussed preliminarily. Authors have also got the fractional dimension of pores of the geotextile with image processing technology.
Keywords:stabilization  soft soil  geotextile  fractional dimension  fatigue damage  finite enement method
