Appendix C Computer Program Axiltr
Program AXILTR, AXIal Load-TRansfeR, consists of a main routine and two subroutines. The main routine feeds in the input data, calculates the effective overburden stress, and determines whether the load is axial down-directed, pullout, or if uplift downdrag forces develop from swelling or consolidating soil. The main routine also prints out the computations. Subroutine BASEL calculates the displacement at the base for given applied down-directed loads at the base. Subroutine SHAFL evaluates the...
Chapter 5 Deep Foundations
5-1. Basic Considerations. Deep foundations transfer loads from structures to acceptable bearing strata at some distance below the ground surface. These foundations are used when the required bearing capacity of shallow foundations cannot be obtained, settlement of shallow foundations is excessive, and shallow foundations are not economical. Deep foundations are also used to anchor structures against uplift forces and to assist in resisting lateral and overturning forces. Deep foundations may...

Depth to the water table and pore water pressure distributions should be known to determine the influence of soil weight and surcharge on the bearing capacity as discussed in 1-4d, Chapter 1. 1 Evaluation of Groundwater Table GWT . The GWT may be estimated in sands, silty sands, and sandy silts by measuring...
