• Thcsc slopes and the proposed embankment geometry has been analyzed for slope stability using cross section <br />pro~idod by Pov<•derhom Coal Company, dated new, G-23-97 and the computer program GEOSLOPE, v 4.10, <br />supplied by the Geocomp Corp. The GEOSLOPE program is based on the Fortan Program, STABL 3, <br />developed at Purdue University. The slope stability analysis utilize the simplified Janbu method of slices for <br />irregular failure surfaces. <br />REACTIVE SOILS <br />Since groundwater in the Cameo area typically contains sulfates in quantities detrimental to a Type I cement, <br />a T}pe II or Tvpe I-II or Type II-V cement is recommended for all concrete which is in contact with the <br />subsurface soils and bedrock Calcium chloride should not be added to a Type II, Type I-II or Type II-V cement <br />under any circumstances. <br />C~ <br />• <br />10 <br />
