章节摘录

插图：7.1.1 The feeble grounds denote the grounds, which are consisted mainly of mud, muddysoil, alluvial filled soil, miscellaneous filled soil or other soil strata with highcompressibility. When within the local range of building's ground exists the highcompressibility soil stratum, that shall be considered as the local feeble soil stratum.7.1.2  When in the field survey, the uniformity, composition, distributing range andproperties for soil of the feeble soil strata shall be ascertained. The condition of drainageconsolidation shall also be understood for the alluvial filled soil. The fundamental factorssuch as the history of piled up, the stability, collapsibility under self-weight etc. shall beascertained and definited for the miscellaneous filled soil.7.1.3 When in the design, the interaction of upper structure and ground shall be takeninto account. The comprehensive analysis shall be earned out concerning with theconfiguration of buildings, the loading conditions, the type of structures and the geologicalconditions to determine the reasonable architectural measures, structural measures and thetreatment method of grounds.7.1.4 When in the construction stage, the attention for the protection of bottom surfaceof mud or muddy soil foundation trench shall be paid to reduce the disturbance duringconstruction. For buildings with comparatively large difference in loadings, hence, theheavy, high parts may be built first, then the light, lower parts may be followed.7.1.5 The structures or the group structures （such as silos, oil tanks etc. ） with compa-ratively large variable loads, their loading velocity shall be controlled and their time intervalof loadings shall be grasped, according to their settlement conditions at the early servicetime, or adjusting the distribution of variable loads to avoid the excessive tilting.

前言

According to the requirements of Document JB [1997] No. 108-Ministry ofConstruction, that the"Code for the Design of Building Foundations"GBJ 7——89, has beenrevised by the China Academy of Building Research together with the Design, theInvestigation and Survey, the Construction, the Research as well as the Teaching relevantunits.In the period of revision, the code revision group carried out various studies on specifictopics, investigated and summarized the recent domestic practical experiences and acceptedthe new research results from concerned domain, meanwhile, the various ways were used bythe code revision group to solicit widespread opinions of the Design, the Investigation andSurvey, the Construction, the Research as well as the Teaching relevant units, the code wasborn out through repeated discussions, amendments and trial designs, finally, the newversion of code was decided after examination.The revised edition of the Code includes 10 chapters and 22 appendices. The mainrevised contents are as follows:The applied range and the calculated method of the ultimate limit states and theserviceability limit states in the design of building foundations are clearly difined; theprinciple of deformation controlling design has been emphasized, satisfying the requirementsfor the serviceability function of building; the classification for rocks and the classificationfor the frost heaving of soils are detailed; the calculated methods for the ground deformationand the resilient deformation of limited compressive stratum are added; the design meth~xt ofrock slope retainer is added; the design method of compound ground is added; the designmethod for raft foundation of tall buildings is added; the design method for the settlement ofpile foundation is added; the design method for foundation pit works is added; the contentsof inspection and monitoring for the ground, foundation are added. The stipulations fordesign of shell foundation have been abolished.
