摘　　要：室内外试验表明素碎石土垫层经土工带加筋后其整体刚度及强度均有明显提高,垫层调整、扩散应力的能力增强。笔者通过试验研究分析并结合实际工程应用,提出太原地区土工带加筋垫层地基承载力实用计算方法,从而进一步推广加筋技术在软弱地基中的应用。Load tests in site and large-scale triaxial tests were carried out for geobelt reinforced gravel cushion. Tests show that the strength and rigidity of reinforced cushion is obviously increased compared with non-reinforced cushion. By the analysis of test results and the practical application, a calculation formula for bearing-capacity of foundation on geobelt reinforced cushion is obtained.
