| The Baoteng highway to be built in Yunnan Province will be an international thoroughfare from Kunming to Myanmar and India and also an important component part of the Asian Highway Network. The Longjiang Giant Bridge is the controlled engineering of this highway, and the landslide stability near this bridge is of vital importance to the building of this bridge. This paper made an analysis of the main landslide—No. 1 landslide in the area of the Longjiang Giant Bridge in such aspects as its engineering geological conditions, mor-phological distribution, distribution mode, formation mechanism and resultant adverse factors and, on such a basis, put forward the idea that the joint structural plane constitutes the main factor controlling the formation and stabil-ity of the landslide of the Longjiang Giant Bridge, with underground water also having some adverse effects. The corresponding prevention and tackling measures are also suggested, which provide important basis for effective control of the landslide and also supply valuable reference opinion to subsequent study of lateral slope of the highway. |
