Guidelines for Using the CPT, CPTU and MARCHETTI DMT for Geotechnical Design. Volume 4. DMT Design Methods and Examples

摘要

Volume IV of the four volume set of GUIDELINES continues Volume III by focusing on the more commonly used design methods that incorporate DMT data. These include consolidation settlement calculations using the Janbu method, immediate settlements, and the lateral loading of piles. It also deals with the use of the DMT in stability problems, such as the bearing capacity of shallow foundations, the bearing capacity of deep foundations, and the calculation slope stability with or without the use of pore pressures. It also includes consideration of various special problems such as pipe trench backfills, the pressures against existing walls, deep compaction control, CBR estimates and liquefaction evaluation. Finally, it contains a section on combining and coordinating DMT and CPT sounding investigations with the currently more conventional exploration methods using the standard penetration test and sampling and laboratory testing. The volume includes an extensive list of references, and example calculations for embankment settlement and rate of settlement. In the Appendices, which apply to both Vols. III and IV, the reader will find copies of 3 key references and 2 computer programs used for data reduction.
