Geotechnical and Geological Engineering. This paper numerically examines the bearing capacity and failure mechanism of a shallow strip foundation constructed above twin voids. The voids may refer to caves, caverns, underground aqueduct or tunnels due to water seepage, chemical reaction or deliberately excavated in soil deposit.
A strip footing is a method of foundation on a solid surface, also called foundation on steel. A soil survey and the size of the house determine whether this method is suitable. Often a strip footing is applied to houses that are built on sandy soil.
In this paper, the ultimate load capacities of shell foundations on unreinforced and reinforced sand were determined by laboratory model tests. A series of loading tests were carried out on model shell footing with and without single layer of reinforcement. The tests were done for shell foundation at different shell embedment depth and subgrade density. The results were compared with those for flat foundations without reinforcement.
Were looking to see whether theyre doing their job. We are not going to figure out how to design buildings, learn to be soils engineers, or pretend we have x-ray vision. Like all parts of a home inspection, while theres stuff we cant do, theres lots that we can.
Strip footing is used to support walls or retaining walls where length is considerably more than the width. The load is considered per unit area per unit length, say 1 m. Consider a strip footing of width B subjected to a uniform pressure q, including self-weight, as shown in Fig.
There are many field situations where at least a moderate increase in the bearing capacity in weak clays is desired. One of the solutions for such situations is stabilization by installing a granular pile or stone column using empirical designs. The plane strain version of a granular pile is a granular trench.
The behaviour of footings on geosynthetic-reinforced soils has been investigated by many researchers through experimental and numerical modelling under stress-controlled or strain-controlled conditions. A new experimental set-up was designed under a stress-controlled condition, with the application of the particle image velocimetry PIV technique. A series of model footing tests was carried out using this equipment to investigate the behaviour of the geosynthetic-reinforced soil below a strip footing.

The report has recommended that some pre-construction measures be taken in order to minimise damage to buildings in collapsible soils, and one such recommendation was excavating the soils and building a conventional reinforced concrete strip footing.
