Abstract Research purposes: For a gigantic project as Algeria East － West Highway，a tremendous amount of surveying needs to be conducted within a limited construction period． The natural factors such as hypsography， geomorphic units and formation lithology，and other external factors，for example，location of project in a foreign country，application of European standard，usage of French as working language，etc，make the engineering geological survey a rarely difficult task． A retrospective on the research of engineering geological survey of Algeria East － West Highway which has already opened to the traffic，is expected to offer beneficial references to projects that are to be realized in the similar regions．
Research conclusions: The analysis allows to reach the following conclusions: ( 1) The unfaverable geological condition is mainly consisted of landslide and karst and the specific rock and soil is mainly formed by marlite and expansive soil． ( 2) The clauses stupulating no arrangement of reconnaissance point in the European Standards need to be neatly applied by engineers． ( 3) The lateral pressure test is irreplaceable for the structural design，the hole pressure test with water level gauge must be adopted in the drilling; and the deep displacement test can offer quantitive basis for the judgement of glide plane． ( 4) The readability of survey report and professional design that are combined in the filing facilitates design examination and constuction management．
