摘要:
简要推导了Mindlin位移的黄土隧道系统锚杆轴力分布的理论解和弹塑性均质土体条件下围岩塑性区半径的理论解.以现场试验结果为依据,从拉拔力作用下系统锚杆的受力特性和锚喷支护中系统锚杆中性点的轴力两个角度出发,分析了黄土隧道中系统锚杆的受力特性及长度优化问题.
Abstract:
The theoretical solution to the distribution of axial force in Mindlin displacement problem and theplastic radius of surrounding rock in the condition of elastoplastic homogeneous soil are deduced.Based on theresults of field test, the mechanical characteristic of systematic bolt and its length optimization are discussed inloess tunnel from the two perspectives of the drawing force and axial force at the location of neural point.Theresults obtained will offer the technical support for the length optimization of systematic bolt in loess tunnel.
