Assessment of the effectiveness of corrective measures in relation to geological conditions and types of slope movement
Summary The General Report consists of three parts. In Part 1, the various types of corrective measures are briefly reviewed. Attention is then concentrated on the two, most used measures; modification of the slope profile by excavation and filling, and drainage. An analysis is made of the optimum positioning of corrective cuts or fills, making use of the influence line concept, borrowed from structural engineering. In this way a neutral point, neutral line and neutral zone are defined for circular and non-circular landslides and for various values of B with respect to the applied change in total stress. Drainage is then discussed in more detail, with particular atteniion being given to horizontal drains and to trench (and counterfort) drains. Performance data for trench drains in the U.K. are then reviewed and analysed. From this a tentative basis for design is developed. In Part 2 the papers contributed to Theme 3 of the Symposium are reviewed. The clogging of drainage systems by siltation or by geochemical effects, is also discussed. Finally, in Part 3, some suggestions are made as to the desirable directions of future research. An extensive list of references is provided.
