陆内沉箱的初步探讨

在本文所介绍的特殊况下:箱形建筑物位于临海的陆内基础较低,海水可以渗入基坑,且其水位受到海域潮汐变化的影响。由于环境和条件的限制,不可能进行干地施工(如围堰方案)或水上施工(如大开挖方案,使内陆基坑与大片水域沟通),就需要借鉴港工的方法,在陆内对该工程进行设计与施工。本文是作者结合亲自参与该类工程的设计与施工所掌握的第一手资料,进行的初步探讨的总结,它将会对今后此类工程建设,具有一定的参考价值。

Primary Approach on the Construction of Caissions Strucutures on Land

Construction of caission structures located on land near sea is impossible both on land (cofferdam)and on water (excavation which connects the foundation trench with wide range of water area) due to the following special conditions : (1)the caission structures hsve lower foundation causing sea water easily going into the trench; (2)water level varies with tile. So the port engineering techniq ues are considered to be adopted for designing and construction. The primary approach and summary presented in this paper is based on the firsthand data obtained from the design and construction of this kind by the authors, which provides reliable basis for the Designing and construction of caission structures on land.
