弹塑性岩体内竖井地压理论

tonsux一ng yant一ne一shuJ一ngd一yol一}un弹塑性岩体内竖井地压理论(ground pres-sure around shaft in elastie一plastie roek)在表土或软岩中掘进竖井时,若岩体只产生弹性变形,岩体是稳定的,不必计算地压。只有在产生塑性及流变变形时,才需要计算地压;竖井各水平截面上地压不等。按轴对称条件求出竖井周边位移,再求出支护位移公式,将它们联立求解,即可得到竖井地压。也可用图解法找到两条位移与应力关系曲线的交点,该点的纵坐标值即为竖井地压(见图)竖井围岩周边位移公式为: “止 U 竖井变形地压计算图 1围岩位移曲线;z支护特性曲线 a(p。s、n,,+。eos叭)厂(尸。+。.eot,t川一sin,.门导 ZG,匕P。+cicot笋,J式中“。为竖井围岩周边位移,m;a为竖井掘进半径,m;P0为原岩水平应力,重力场条件下,P0一六yI1,MPa;c,为第i层岩石粘结力,MPa;尸b为支护抗力,等于围岩作用在支护结构上的径向压力,但作用方向相反,MPa;笋,为第i层岩石内摩擦角;G.为第!层岩石剪切弹性模量;MPa。 竖井筒形支护特性方程为: l一群2厂bZ+a,尸1。, z,‘一二六舟}头‘-共一一IP,b EL右2一aZx一尸J“”式中u。为支护外半径表面的径向位移,支护与围岩密贴的情况下,“,一“、;E及产分别为支护材料的弹性模量及泊桑比;“为支护内半径,m;b为支护外半径,m;尸二为竖井变形地压,尸。一尸b,MPa。 (高磊)
