摘要
目前我国现行规范对砂砾石层等覆盖层的固结灌浆检查标准,仍缺乏统一的规定。通过对灌浆体前后波速提高幅度,对比载荷试验、超重型动力触探检测砂砾石层等覆盖层固结灌浆体承载力和变形模量的提高幅度,可以给出砂砾石层固结灌浆体波速检测合格标准,以判断固结灌浆体承载力和变形模量是否满足设计要求。
At present,the current specification with the consolidation grouting examination standards for the overburden layers,such as gravel layer,is still lack of unified regulations.Compared the increased range of wave velocity between the pre and post grouting,the bearing capacity and the deformation modulus of consolidation grouting body of the overburden layers,such as gravel layer,tested by load test and extra heavy dynamic sounding,the qualified standard of wave velocity detection for consolidation grouting body of sandy gravel layer is obtained to determine whether the bearing capacity and the deformation modulus of consolidation grouting body meet the design requirements.
