Abstract: The program HEAVE is a one-dimensional computer program for approximate analysis of vertical movements of swelling foundation soils beneath permanent structures caused by changes in vertical loads and/or the moisture profile. The program is applicable to slab, long continuous, and circular shaft foundations. Results of both one-dimensional consolidometer swell tests and soil suction tests may be used in HEAVE. The program considers effects of soil overburden pressures and structural loads, heterogeneous soils, and saturated or hydrostatic equilibrium moisture profiles on the computed heave. An arbitrary final soil suction profile may also be input if soil suction results are available. Differential heave may be estimated by comparing heaves computed for different soil strata and vertical loads. HEAVE can estimate the movement of circular drilled shaft foundations, the maximum tension force in circular shafts from heave of surrounding swelling soil, and the restraining force provided by the underream (a bell or enlargement of the shaft base). Upward movement is assumed negligible if restraint exceeds the uplift thrust from surrounding swelling soil. Estimates of shaft movement can be made for moisture migrating down the shaft from the ground surface, moisture migrating from an intermediate zone such as from a relatively thin, pervious sandy stratum, and moisture migrating upward from below the base of the shaft such as from capillary rise of a rising water table.
