1.0.1 This code is formulated with a view to implement the national technical and economical policies in design of the building grounds, foundations, that the design can be accomplished with safety and usability, using advanced technology, with economy and rationality, assuring the quality and protecting the environment.
1.0.2 Design of the building grounds, foundations must persist in the principles of suiting measures to local conditions, using local materials, protecting the environment and economizing on the resources; the design shall be painstakingly performed, considering the factors comprehensively as the type of structures, the availability of materials and the construction conditions etc., according to the geotechnical survey data of rocks, soils.
1.0.3 This code is applicable to the design of grounds, foundations of industrial and civilian buildings (including structures). For the design of grounds, foundations in the collapsible loess, the perennial frozen soil and the swelling soil, as well as, under the action of seismic load and vibrating load of machines, that the requirements in the current relevant standards or codes of the nation shall also be complied with.
1.0.4 When this code is used for design, the values of loads shall meet the requirements in the current National Standard “Load Code for the Design of Building Structures” GB 50009; the calculation of foundations shall also meet the requirements of the National Standard “Code for Design of Concrete Structures” GB 50010 and “Code for Design of Masonry Structures” GB 50003. When the foundations are laid in aggressive environment or are subjected to temperature influence, that the requirements in the current relevant mandatory standard of the nation shall also be complied with, and the corresponding protective measures shall be taken.
