History Cases of Geo-mechanics Failures
Introduction
Proper design of foundation required a strong basis on mechanics, but should also be …show more content…

There was the under-design of the diaphragm wall and the waler connection under-design in the strutting system. These errors lead to the failure of the 9th level strut-waler connections together with the inability of the overall temporary retaining wall system to resist the redistributed loads as the 9th level strutting started to fail. Disastrous collapse of part of the highway then followed which occurred step by step preceded by a chain of events
Why:
Several mechanical and administrative factors led to the collapse. One factor was the failure to demonstrate the required level of care and monitoring during construction. Warnings of the forthcoming collapse were seen from an early stage, but were ignored or taken lightly. Another factor contributing to the collapse was the appropriate design reviews notably the under-design of the diaphragm and that of the waler connections. There were inadequate contingency and corrective measures these designs and designs were not sufficiently robust to account for the risks recognized.
Another cause of the failure was overloading of the temporary works which coincided with the digging of a prop below the ninth level struts which was installed using jet grouting …show more content…

Under feasibility and planning, we may have factors such as unrealistic expectation of development on selected site, insufficient geotechnical investigation for the given development, unrealistic soil performance for given development and development constraints and restriction leading to inappropriate equipment or techniques. Consultant’s design and specifications may impose unrealistic demands on solutions. Client’s brief may fail to convey end usage; insufficient geotechnical investigation could lead to inappropriate design while on site conditions may be different to assumptions or what has been written. On the other hand flawed design and insufficient site preparation may lead to construction of structures which are likely to fail in the near future. Poor methodology and planning practices include: inappropriate or poor choice of equipment, lack of experience and understanding, lack of awareness and consequence of failure, bad workmanship and shortcutting and lack of
