摘要
在高填方地基的沉降中,填筑体的沉降要占较大比例.对于填筑体的自身压缩变形计算,目前还没有通行的方法.以康定机场某段高填方填筑体为例,对土面区进行了施工监测,采用龚帕斯生长曲线模型对高填方地基沉降进行了预测,并与对数模型、双曲线模型进行了对比,发现用龚帕斯生长曲线模型预测效果较好.
A large proportion is occupied by the settlement of filling embankment in the settlement of high-fill foundation.For its own compression settlement of filling embankment,There is no general deformation calculation method.Take section B of Kangding airport high-fill filling embankment for example,the construction of soil surface areas are measured,and Gompertz living curve model is used to forecast the high-fill foundation settlement.Compared with Logarithm model and Hyperbolic model,we can find out that the effect of settlement forecasting of Gompertz living curve model is best.
