Abstract

The paper examines retaining structures consisting of thin shells filled with soil or other material (in a varying degree providing structural integrity), keeping the soil from failure and sustaining the complex of technological loads. Filled shells structures serve as a constructive base for retaining structures and are used in various construction areas (industrial, transport, hydraulic engineering). The technique is proposed which allows to determine structural design model at an early design stage considering the key initial design parameters: overall dimensions of the structure, acting loads and the soil base properties. Based on the proposed ratios an example is given of the structure classification and the design model choice depending on its dimensions, depth of embedding and the magnitude of soil base design resistance. Extreme principal dimensions ratios of the structure are shown at which there is a need of fixing the structure in the soil, dependencies for determining setting depth are given.
