Abstract

 
 
 The results of studies of the reactive capacity of the soil base of a gravity- type quay-wall on the basis of the method developed for calculating the “structure - soil base” system are considered. The method proposed allows determining the reactive capacity of the soil base in conditions of mixed stress state model (limit and sublimit stress state of the soil base) under and around of the base of the foundation structure in a wide range of loads of lateral earth pressure. The transformation of limit and sublimit stress state zones of the soil base on the basis of numerical modeling is presented which shows an increase of the sizes of limit stress state and a decrease of the sizes of sublimit stress state.
 
 
Highlights
Gravity-type quay-walls are the most common type of walls used for harbor berths
It should be noted that the increase limit loads cause the loss of the reactive capacity of the soil base under the base of the foundation structure
The model proposed of the interaction of a gravity-type quay wall with the soil base is based on the following presupposition: 1. The soil base interacting with the base of the foundation structure includes zones of limit and sublimit stress state
Summary
Gravity-type quay-walls are the most common type of walls used for harbor berths. Reliability of the soil bases is one of the main factors in the design and the reconstruction of gravity-type quay-walls. Purpose of the study: to present the study’s results of the reactive capacity of the soil base of gravity-type quay-wall on the basis of developed calculation method “structure – soil base” system [1] taking into consideration features work of the structure and soil backfill. The model considers limit and sublimit stress state of the soil base under and around the foundation structure.
