软土地基水下筑堤施工期之动态监测

Construction Monitoring of an Underwater Embankment on Soft Soils

随着沿海地区经济的快速发展,需要大量的建设用地。由于用地指标的限制,这些地区经常需要在海滩的软土地基上进行围海造地工程。类似工程的堤基土物理力学性质差,施工期和工后沉降量均较大,为控制围堤吹填加载速率,保证围堤施工期断面稳定,设计一般会要求进行施工期动态监测。

With the rapid economic development of the eastern coastal provinces, large quantities of land are needed as constructions sites. Due to the limitations of the commercially available land, many engineering projects of near the sea tend to reclamation of the tidal marsh with soft soils with embankment encircled dredged materials. These embankments are usually mar ginally stable due to its poor soil properties. Large construction settlement and post construction settlement are expected. The construction monitoring is necessary in order to control the rate of dredge filling and the stability of the embankment.
