Landslide hazards in Garhwal Himalayas, Mussoorie Slide - a case study

effectiveness is achieved if the granular material is compacted in thin layers. The effects are twofold, improved drainage and soil reinforcement. Methods to calculate the stabilising effects for different applications are given.
Following numerous debris avalanches in Blue Ridge Province after heavy rainfall in August 1969, a study was undertaken to determine which geotechnical properties of the soils and rocks were important to promoting such slope failures. Geomorphological and geotechnical studies were carried out on 21 first order drainage basins selected randomly and classified as unstable on the basis of topography. The nature of both the soil cover and the underlying bedrock is seen to be important to stability.

936384 Murangala landslide, Kenya Davies, T C; Nyambok, I O Environ Geoi V21, N1/2, April 1993, P19-21
Failure analysis of a landslide resulting in fatalities is presented. Samples from the site were taken for geotechnical characterisation and surface configuration of the slide examined. A combination of factors is considered responsible for the slide, including a high, steep slope of deeply weathered volcanic soil with a highly sorptive surface layer and additional loading by soil transported from a man-made excavation. Saturation of the top stratum of excavated soil due to heavy rainfall provided the failure trigger. Socioeconomic aspects of developments in such areas are examined. 936385 Landslide at the B 421 near Gehlweiler (In German) Jahnel, C; Koster, M Feisbau V l l , N3, June 1993, P128-133
A massive slope failure in March 1988, covering about 3/4 of the height of the valley slope of sandstone, siltstone, and claystone rocks, threatened the B 421 highway. Movement of this unstable slope was attributed to prolonged rainfall. Remedial work on the failed slope and adjacent slide-prone areas is described. A combination of excavation and reprofiling, local anchoring and pattern rock nailing, and heavy protection nets and fences was installed. 936386 Geotechnical design of a stabilized uranium mill tailings pile in Spain (FUA) Fuente Martin, P; Jiminez Juan, A; Santiago, J L Felsbau V l l , N3, June 1993, P141-147
The old F U A mill has left about 1 million cubic metres of tailings. Closure of the pile is necessary to minimise risk to public health. Pile stabilisation in place was the chosen method. Geotechnical considerations include slope stability and pile settlement, groundwater protection, radon barrier, and protection from effects of surface water. Penetration tests and auger sampling were used in geotechnical characterisation of the pile. Slope reprofiling and recompaction and a composite cover of natural materials have been designed, and finite element stability and settlement analyses carried out. 936387 Geo-Anchors Broms, B B Geotext Geomem V12, N3, 1993, P215-234
Geo-Anchors, constructed by lining a narrow trench with high strength geotextile and adding a core of coarse granular material then backfilling,are proposed to improve stability of slopes or reduce earth pressure on retaining structures. Maximum
Shallow failures of some of the 31 road embankments on the Wyllies Port-Sibisa road in Venda have been studied. Annual rainfall is about 3200mm, mostly in thunderstorms, annual evaporation about 1800ram. Weathered lava is the dominant construction material. Surficial sloughing associated with prolonged precipitation and poorly compacted embankment flanks is the most frequent failure mechanism. Both conventional and finite element stability analyses have been carried out. It is recommended that design codes be updated to include this failure mechanism and that all embankments with annual rainfall °1000mm be checked for its development. 936389 Monitoring of openpit mine face approaching a river Juranka, T; Silar, J; Rozsypal, A Proc 3rd International Symposium on Field Measurements in Geomechanics, Oslo, 9-11 September 1991 II2, P527-536.

Transport links, pipelines, and the Belina river (in an unsealed concrete bed) are carried by an embankment around the periphery of a large lignite mine near Most, Czechoslovakia. The 5 million cubic m pillar protecting the transport corridor has recently been excavated without adequate pre-mining planning. Field measurements and finite element analysis indicate the slope is in an unstable state. Several remedial measures, all drastic and expensive, have been suggested. The danger of inadequate planning is demonstrated. 936390 Landslide hazards in Garhwal Himalayas, Mussoorie Slide - a case study Mehrotra, G S; Bhagat, N C, Sarkar, S Proc Ninth Asian Regional Conference on Soil Mechanics and Foundation Engineering, Bangkok, 9-13 December 1991 V1, P409-414. Publ Thailand. Southeast Asian Geotechnical Society, 1991
Landslide problems in the area of the Mussoorie-Chamba bypass have led to subsidence and surface movements causing structural damage. The slope forming material is weathered crushed and fractured dolomitic rocks. Geological and geomorphological studies have been carried out and slope movements monitored. Control mechanisms specified include modification of the drainage system, gabion walls, breast walls, sealing of cracks, and grout columns. The slope has been covered in parts with geogrid, both to restrain the debris and promote vegetation. 936391 Slope stabilization measures for the Kuala Lumpur-Karak toll highway Moh, Z C; Wijemunige, P; Khanchanusthiti, R Proc Ninth Asian Regional Conference on Soil Mechanics and Foundation Engineering, Bangkok, 9-13 December 1991 V1, P419-424.
