Construction And Its Control Of A Group Of Open Caissons

The thesis expatiates on the choice of scheme and the plan to construct a group of open caissons in the field of soft soil, introduces the methods to control effectively the quality of construction throughout the fabrication of open caissons, the preparation for sinking and the course of sinking, especially the speed of sinking, stability of open caissons, apophasis of the soil inside the caissons, etc., checks the magnitude of sinking of ground outside the open caissons and contrasts with the real results, discusses the problems happened in the course of construction, summarizes the difficulties, characters and emphasis of construction of a group of open caissons, these put forwards the rational scheme to construct open caissons in groups in the field of soft soil and the methods to control effectively the quality of construction.
