Thank you mr.charles , well, I agree with answer of my dear brother eng. Hatem . So the Design philosophy that the design loads with adequate geotechnical and structural capacityand with tolerable settlements in conformance to the performance requirement of the structure. The following shall be satisfied
• Ensure that there is an adequate margin of safety against the possibility of pile failure under
working loads.
• Limits settlement of the foundations and the differential settlement between the foundations
(abutment/piers) to values that are consistent with performance requirements of the
superstructure.
• The overriding influence of site geology, construction methodology and quality control adopted
on rock mass properties and overall design shall be recognised in the design of CIP piles.
• Limit the mobilisation of peak side resistance when there is uncertainty as to the ultimate
capacity in end bearing in the design of CIP piles.
• In addition to these above, for piles socketed into rock, an iterative design methodology
reviewed on the basis of socket inspections to validate the geotechnical model and the design
assumptions needs to be ensured. In particular, the load transfer mechanism between the
shaft and the base adopted in design needs to be justified on the basis of the socket
inspections.
• Site inspection and verification of constructed sockets by an RPEQ qualified Geotechnical
Engineer or an Engineering Geologist with over10 years’ experience in similar civil
engineering construction works is mandatory. Sign off (certification) shall be by a RPEQ
Geotechnical Engineer.
70 tons lorry is the design live load with case of loading
so you can use it as actual test
