摘要
在大面积围填海造地工程中,随着施工技术的发展,利用吹填淤泥作为填料得到了大量的应用,而相应的沉降计算还无法满足实际需要,沉降量只能凭借经验预估。利用饱和土的水土二项性进行分析,通过计算土体加固前后含水率的变化,从而进一步计算土体的沉降量,得到沉降计算公式,并利用实际工程验证了计算公式的正确性。
In the large area enclosed land reclamation project, with the development of construction technology, the use of dredged sludge as filler gets a lot of applications. But the corresponding settlement calculation can not meet the actual needs, and the estimated settlement amount only by virtue of experience. Using the twophase of saturated soil＇s water and soil properties, we calculate further the amount of soil subsidence and obtain the settlement formula by calculating the change in the moisture content of the soil before and after reinforcement, which is validated by actual project＇s settlement monitoring data.
