土工格栅在铺设的过程中有许多事项是需要我们去注意的,不仅如此还有回填土的操作更是有讲究的。在铺设完毕后,土工格栅需要回填土,目的是为了加强作用力,对该工程的影响仍然很大。
In the process of laying geogrid, there are many matters that need our attention, not only that, but also the operation of backfill soil is particular. After laying, the geogrid needs to be backfilled in order to strengthen the force, which still has a great impact on the project.
网格孔径与填充孔径不同,适用范围也不同,在施工时应首先考虑二者的比例关系。试验表明,在土工格栅孔径比为0.05时,存在一个最佳的土工格栅孔径匹配关系,以获得界面摩擦角最大值。
The application range of grid aperture is different from that of filling aperture, so the proportion of them should be considered first in construction. The test results show that there is an optimal matching relationship of geogrid aperture when the aperture ratio of geogrid is 0.05 to obtain the maximum value of interface friction angle.
密实度、填料含水率、土工格栅孔径等因素影响界面强度。随着压实度的增加,界面摩擦角增大,填充水含量增大,界面摩擦角减小,界面摩擦角通常小于界面摩擦角。摩擦系数一般在0.82~0.95之间,含水率最高可达12%,国内外相关试验结果也不例外。
The interface strength is affected by the compactness, the moisture content of filler and the aperture of geogrid. With the increase of compaction degree, the interface friction angle increases, the filling water content increases, and the interface friction angle decreases, which is usually smaller than the interface friction angle. The friction coefficient is generally between 0.82 and 0.95, and the highest water content is 12%. The relevant test results at home and abroad are no exception.
填方水含量对界面摩擦角有很大影响。填方接近饱和时,筋土的内摩阻力角减小18.5%,内摩阻力比为0.51。加固土工程中的排水问题应引起重视,在湿雨地区或高液限粘土作为填料时,加固土界面摩擦系数应根据加固土界面摩擦试验确定,或采用低界面摩擦系数。
The filling water content has a great influence on the interface friction angle. When the fill is nearly saturated, the internal friction angle of reinforced soil decreases by 18.5%, and the internal friction resistance ratio is 0.51. In wet rain area or high liquid limit clay as filler, the interface friction coefficient of reinforced soil should be determined according to the interface friction test of reinforced soil or adopt low interface friction coefficient.
