| 摘 要： | 利用两种经验公式法对哈尔滨绕城高速公路试验段软土地基沉降观测数据进行了计算,对计算结果与工程实际情况进行了对比分析,发现沉降过程、最终沉降量、沉降速率和路堤横断面差异沉降等较为符合工程实际,认为经验公式法在季冻地区软土地基沉降预测的应用有实用意义。

| Abstract: | Two experience formula methods were used to calculate the observational settlement data of soft-soil groundwork in the ring highway of Harbin. Calculation result and the actual data were compared. Result shows that the prediction result of settlement process, final settlement, settlement velocity, and differential settlement of embankment cross-section accords with the actual data. Therefore, the experience formula methods are applicable to the settlement forecast of soft soil groundwork in seasonal freezing areas. |
