摘要
土工格室在国内高速公路工程建设中得到了实际应用,并对其加劲效果进行了分析研究。通过某高速公路试验路段,在基层中铺设增强土工格室,与未铺设的作对比,利用现场承载板检测,可见土工格室可使当量回弹模量提高50%以上。再通过BISAR软件反算出路面基层的单层模量,得出土工格室能使单层回弹模量提高2倍以上。利用贝克曼梁弯沉仪,也可得出土工格室使弯沉降低20%以上。
Geocell has been used in the highways engineering construction in China, and its reinforcement effect has been analyzed and researched. Taking the testing section of some highway for example, the base with geocell can make the resilient modulus improved by about 50% through the in-site bearing board test. Then, according to back-analysis of BISAR software, geocell can make the resilient modulus of single layer improved by 2 times at least. And geocell also can make deflection decreased by above 20% through Beckman Beam Deflectometer.
