Such a procedure is given in table 1-1. <br />implementing this procedure is presented in subsequent <br /> <br />design and can be <br />for any partic- <br />Information for <br />chapters, <br /> <br />(4) The method of construction must also be considered, In the <br /> <br />Table 1-1. General Design Procedure <br /> <br />~ Procedure <br /> <br />1 Conduct geological study based on a thorough review of available data in- <br />cluding analysis of aerial photographs. Initiate preliminary subsur- <br />face explorations. <br /> <br />2 Analyze preliminary exploration data and from this analysis establish <br />preliminary soil profiles, borrow locations, and ecban~~ent sections. <br /> <br />3 Initiate final exploration to provide: <br /> <br />~. Additional information on soil profiles. <br />b. Undisturbed strengths of foundation materials. <br />c. More detailed information on borrow areas and other required <br />excavations. <br /> <br />4 Using the informa~ion obtained in Step 3: <br /> <br />a. Determine both embankment and foundation soil parameters and <br />refineJPreliminary sections where needed, noting all possible <br />problec areas. <br />b. Compute rough quantities of suitable caterial and refine borrow <br />area loca~ions. <br /> <br />. <br /> <br />5 Divide the entire levee into reaches of s~~~ar fou-~cation con~i:ions, <br />emba~ent height, anc fill me~erial and assi~ a t~~ical tri~l <br />section to each reach. <br /> <br />6 Analyze each trial section as needed for: <br /> <br />a. Unuerseepage and through seepage. <br />b, Slope stability. <br />c. Settlement. <br /> <br />7 Design special trea~ent to preclude any proble=s as dete~i~ed <br />from Step 6. <br /> <br />8 Based on the results of Step 7, establish final sections for each reach. <br /> <br />9 Co~pute final quantities needed; deter~~ne final borrow area locations. <br /> <br />10 Design embankcent slope pro~ection. <br /> <br />1-2 <br /> <br />. <br />
