  1. In order to assure the bonded - strengthened beams to have ductility and fully exert the compressive capability of concrete, the paper deduces the lower limit compressive height used in design from the plane section assumption and theory of limit destruction. the lower limit compressive height is when the strain of compressive edge fiber reaches its peak value ( 0. 002 ) and the externally bonded material reaches its limited strain ( 0. 01 )

    由平截面假定和界限破壞理論，並保證粘貼加固梁具有一定的變形能力和較為充分地發揮混凝土的抗壓性能，本文以受壓區混凝土邊緣應變達到峰值應變（ 0 . 002 ） ，而加固材料應變剛好達到極限值（ 0 . 01 ）的界限破壞時混凝土受壓區高度做為粘貼加固梁設計高度的下限值_ （ c0b ） h 。
  2. The paper presents a detailed numerical analysis to elucidate the failure pattern of the pit wall, the mechanism of the soil - nailed supporting system and its spatial behavior. firstly, a typical two - layer sand - cobble deposit was chosen for a detailed 2d - fem study. it was shown that due to the distinct behaviors of the upper soft sand layer against the much stiffer lower cobble layer, a bi - linear plane failure was recommended to be used in the limit equilibrium analysis
