摘　　要：港区道路与堆场常位于深软土地基上,沉降量大,提出一种提高港区道路与堆场承载力方法。通过现场试验段试验,采用贝克曼梁进行弯沉测定,分析研究土工格栅对提高港区道路基层结构整体性效果。研究结果表明,土工格栅对港区基层较好的加固效果,加固效果达到36%。此外,土工格栅的不同位置起不同加固效果,土工格栅放置越向上面层,弯沉值越小,加固效果越好。在此基础上,提出土工格栅加固港区道路基层方法。The pavement and storage yard on port is located in depth soft soil foundation; the settlement is large,so that the approach of enhancing the bearing ability of the pavement and storage yard on port is put for ward. Field experiment of test section was carried out. Deflection was determined by Beckmann beam,the pavement base on port reinforced with glass fiber geo-grid was analyzed. The test result shows that the effect on the base on port reinforced with glass fiber geo-grid is satisfied,the ratio reaches 36%. In addition,the effect of the position reinforced with glass fiber geo-grid is different,and the better effect of reinforcement with glass fiber geo-grid is the toper of the base on port. On this basis,the approach of the base on port reinforced with glass fiber geo-grid is reference on design and construction.
