一、前言钢丝网水泥压力管内由于多向限制,特别是园周方向限制了自应力水泥砂浆的膨胀而产生预应力,称为自应力钢丝网水泥压力管。这次试验是通过内径为350毫米和800毫米的离心法生产的自应力钢丝网水泥压力管在水养过程中的应变测定和水压试验。对自应力钢丝网水泥压力管的自应力值,弹性模数及泊桑比进行了探讨,并推求了自应力钢丝网水泥压力管的强度计算方法。 I. INTRODUCTION Due to multi-directional restrictions in the pressure pipe of steel mesh cement, especially in the circumferential direction of the park, the self-stressing cement mortar expands to generate the prestress, which is called self-stressing steel mesh cement pressure pipe. This test is a strain measurement and hydrostatic test of a self-stressing steel mesh cement pipe produced by centrifugation with inner diameters of 350 mm and 800 mm during hydration. The self-stress value, modulus of elasticity and Poisson’s ratio of self-stressing wire mesh cement pressure pipe are discussed. The calculation method of self-stressing steel wire pressure pipe strength is deduced.
