Abstract

Abstract

The Lancangjiang Bridge is one of the controlled engineerings on the under-construction Dali-Ruili Railway. Along the bank slopes at which the bridge site is located there are greatly developed long-extending dip-slope joints and nearly vertical joints, The excavation area of the bridge site on right bank is below a group of large dip-slope structural planes, so the slope stability is directly related to the suitability of bridge site. Comprehensive studies show that excavation on right bank will be like to induce slip and tension crack failure affected by the dip-slope structural planes and to cause great displacement along extraversion structural planes, and even instability on whole slope, with which the specialized engineering management should be taken to deal. On the contrary, rock masses on left bank are of a relatively stable structure, and the displacement induced by engineering will mainly take place on shallow surface of excavation site, with slight deformation and limited influence area.
