摘 要: 本文通过理论和实测分析对格栅加筋地基的沉降和承载力进行分析。格栅加筋的沉降分析采用有限元分析方法,结果表明格栅采用2~3层较为合理,施工时应采用包裹型。沉降分析表明,格杨加锚地基可以减少沉降约35%,减少不均匀沉降63%。同时格栅加篇可以迅速形成施工平台,同时可以明显提高路基的承载力。 The paper analyzes the settlement and bearing of the screen reinforced foundation bytheory and actual measurement. The screen reinforced settlement shall be analyzed by finite ele-mcnt method. The results show 2~3 layers for the scrccn are reasopnablc. Wrapping type shall beuscd during the construction. The analysis of settlement shows screen relnforced foundation canreducc about 35 % of settlement and 63 % of unequal settlement. At the same time,the screen re-inforcement can rapidly form the construction platform and can obviously improve the bearing ofsubgrade.
