Engineering geological investigations for pile foundations on a deeply weathered granitic rock in Hong Kong
Summary In weathered rocks the determination of founding depth for the foundations of major structures is complicated by the highly variable nature of the material. In order to ensure that the properties of the soil or rock mass on which the structure is to be founded correspond to those assumed in design it is necessary to unambiguously characterise the mass. This paper outlines a scheme used to characterise the weathered rock mass and describes the engineering geological logging of the large diameter pile foundations on a deeply weathered granodiorite for a series of bridges in the New Territories, Hong Kong. The results of field and laboratory index and engineering tests carried out to determine the characteristics of the foundation rock are discussed. The drawbacks of use of RQD, percentage core recovery or probing tests as a means of determining and proving founding depth of piles are also discussed.
