Caisson (engineering) - Wikipedia
网页A caisson is sunk by self-weight, concrete or water ballast placed on top, or by hydraulic jacks. The leading edge (or cutting shoe) of the caisson is sloped out at a sharp angle to aid sinking in a vertical manner; it is usually made of
Enhanced static simulation process of caisson sinking using the …
网页2023年10月15日 · Caisson sinking is a vital process in marine engineering, and accurate simulations are crucial for predicting and preventing potential accidents or failures. Current numerical simulations necessitate measured engineering …
Caisson Method - SpringerLink
网页2022年12月27日 · The function of the caisson cutting edge is to reduce the sinking resistance of caissons, and caisson walls mainly bear outside water-earth pressure and their dead weight (Fig. 1). The caisson method, characterized by simple operation and fewer devices, is suitable for drift sand, mucky soil, …
A new installation technology of large diameter deeply-buried caissons …
网页2022年7月1日 · For underpinning in free air method, caisson shafts are sunk into ground by progressively excavating, then installing pre-cast concrete segmental rings with watertight gaskets, or using spray-concrete lining (SCL). It is mostly used in dry and stable ground conditions (Schwamb, 2014, Spagnoli et al., 2017).
Active control method for the sinking of open caissons: A data …
网页2022年8月1日 · This paper proposes a key index of open caisson sinking, the sinking by earth excavation index (SEI). Then, a time series prediction model of SEI based on convolutional neural network (CNN) was established, and an active control method with a data-driven strategy was proposed based on this model.

网页A primary object of the present invention is, therefore, to provide a caisson sinking method which can effectively sink the caisson while accurately maintaining the normal attitude of the...
Experiences with the Caisson Sinking Method
网页The caisson sinking method is one way to construct underground concrete structures, such as bridge piers, intake structures, pump houses and dumper pits, in soils with a high water table. In this method, a caisson is constructed on the unexcavated site, with the caisson comprising only the walls of the final structure.
Examples of open caisson sinking in Scotland | Proceedings of …
网页2015年5月25日 · Open caisson-sinking techniques permit a shaft structure to be progressively sunk, either under its own weight or with the aid of caisson jacks, in a controlled manner from the surface to a predetermined depth. The technique is suited to shaft construction through weak soils, high- to extremely high …
Initial Sinking Method for Large Open Caisson in a Highway …
网页2018年8月3日 · Open caisson-sinking techniques is to let the structure gradually be sunk either under its own weight or by excavation of the soil inside it. The initial sinking method of a large scale open caisson is an essential consideration in their design because almost all the cases of crack occur at the very beginning of sinking.
Numerical Simulation on the Whole Sinking Process of Open Caisson …
网页2021年2月25日 · In this study, we proposed an improved soil-water-caisson interaction algorithm with the method of smoothed-particle hydrodynamics (SPH). This algorithm dealt with the support domain truncation of the particles near the blade and applied δ − SPH to avoid the pressure fluctuation.
