In the second step, by successively executing excavation-timbering analyses, when excavation of a final excavation zone is completed, a mean value of nodal point displacements of respective elements located at a boundary between the natural ground and the timbering in evaluation objective excavation zones, and a mean value of radial stresses are calculated as a wall surface displacement u<SP>L</SP>and a timbering reaction P<SB>i</SB><SP>L</SP>, respectively. In the third step, an allowable natural ground distortion curve is created based on the relationship between an allowable wall surface displacement u<SB>a</SB>and timbering internal pressure P<SB>i</SB>calculated by using an allowable wall surface distortion ε<SB>θ</SB>,<SB>a</SB>applicable to the natural ground. In the fourth step, an allowable acting ground pressure line is created from a timbering reaction P<SB>i, max</SB>assumed when a tangent directional stress σ<SB>θ</SB>at an internal edge of the timbering is equal to an allowable stress σ<SB>a</SB>of a timbering material. In the last step, it is determined whether or not a point determined by the wall surface displacement u<SP>L</SP>and the timbering reaction P<SB>i</SB><SP>L</SP>falls in a region enclosed by the allowable natural ground distortion curve, the allowable acting ground pressure line, and a natural ground characteristics curve.  <P>COPYRIGHT: (C)2009,JPO&INPIT
