METHOD FOR CONSTRUCTION OF WALLING IN EARTH Russian patent published in 1997 - IPC

FIELD: construction engineering. SUBSTANCE: this can be used in erection of buried structures of various applications. According to method, components which constitute walling are of various rigidity in depth EJ, where E - modulus of deformation of walling component, J - moment of inertia in lateral cross-section of walling component. Each walling component has at least two sections of different rigidity. One of these sections is made in zone where walling is subjected to maximal bending moment over length which is equal to (4-20)d, where d - maximal cross-sectional dimension of walling component with rigidity corresponding to maximal value of bending moment. Rigidity of each subsequent section of walling component is assumed as corresponding value of bending moment at boundary of adjacent section of higher rigidity. Length of each section with lesser rigidity is assumed as not exceeding (10-5-)d. EFFECT: high efficiency. 4 cl, 5 dwg
