FROST HEAVE SUGGESTION

A modified figure is presented (of a previously published representation) which includes the effect of a geothermal gradient (1 deg. F/100 ft) and the effect of a mean annual ground surface temperature (50 deg. F). The result is an upward shift of the 32 deg F and 3 deg F isotherms. It appears that the 32 deg F isotherm approaches steady state conditions close to a maximum depth of 39 feet. Attention is directed to a technical paper which suggests that the increase in temperature due to a geothermal gradient of 1 deg. F/ 100 ft. may be conservative. It is suggested that the gradient may approach 2 deg F/ 100 ft or more. The same technical paper also provides simpler techniques for obtaining steady state temperatures.
