本文提出了一种利用统计分析方法对公路路基工后沉降进行早期评价的方法,并对静载试验方法进行了改进,即延时静载试验。根据现场试验数据计算了长时间加荷后的残余沉降Sr(t)和沉降速率Vs(t)。测试程序和相应的实验验证。基于实测数据,建立了最终残余沉降与工后实际沉降的概率模型。建议的时间延长的负载测试为基础的评估系统已通过三个运营和有据可查的路段进行了验证。根据验证结果,可以在早期准确评价施工质量,并及时采取相应的补救措施。
This paper proposes an incipient assessment method for postconstruction settlement of highway subgrade by using statistical analysis approach with an improved static loading test method, time-extended loading test. The time-extended loading residual settlement Sr(t) and settlement rate Vs(t) are calculated from the field test data. The test procedure and the corresponding experimental validations are presented. Based on the field test data, a probabilistic model is built to bridge the final residual settlement and the actual postconstruction settlements. The proposed time-extended loading test based assessment system has been validated through three operating and well-documented road sections. According to the validation results, the construction quality can be accurately evaluated at an early stage and the corresponding remedial measures can be applied timely.
