中文摘要：

介绍一种新的地基处理技术-土工袋的加固原理。用土工布缝制的编织袋，将素土、碎石、建筑渣土等粒状材料包裹起来，形成具有一定强度的土工材料。其加固原理是编织袋张力使袋内粒状材料产生围压，增加了土体的强度和模量。土工袋被广泛应用在构筑物的基础、护坡结构、挡墙结构和路基沟塘填筑中。

英文摘要：

The reinforcement theory of Soilbags, a new earth reinforcement method, is introduced. It is geo-material, woven by geotextile, in which soil, broken stone and architecture sediment, etc. , are wrapped. The strength and modulus of soil is enhanced by the confined pressure of particle materials in bags, induced by the bags＇ tension. Soilbags are widely used in building foundation, slope-protected structure, retaining wall and pond construction in roadbed, etc..
