高填方填筑体处理效果评价研究

在高填方工程中,湿陷性黄土作为填料,对其填筑体处理效果评价开展研究至关重要.以95％的压实度标准,对填筑体处理效果从室内试验、K30检测、载荷试验、浸水载荷试验、回弹模量、物探(面波)检测等指标进行综合评价.处理后的填筑体得到很好的压实效果,湿陷性已完全消除,满足各项设计要求.处理效果评价说明了施工方法和参数的合理性与有效性；试验所得相关指标可为沉降计算、边坡稳定性分析、施工质量控制提供参数依据.

Study on Treatment-effect Evaluation in High-fill Project

In high-fill project by collapsible loess filling,it is very important for engineering to study on treatment-effect evaluation.Based on 95% of compacting standard,the authors make comprehensive evaluation on the treatment-effect from indoor test,K30 test,load-settlement test,soaking load-settlement test,rebound modulus and geophysical detection.The high-filling obtains good compacting effect and clears up collapsibility which can meet design demands.According to treatment-effect evaluation,the construction method and parameters are reasonable and effective.Meanwhile,the parameters from test can be references for settlement calculation,slope stability analysis and quality control.
