摘要
从锚固系统的组成出发,考虑锚杆灌浆体界面强度和灌浆体岩土体界面强度对全长粘结式锚杆抗拔力的影响,以及浆体与岩土界面的塑性区发展,推导得到全长粘结式锚杆的抗拔力计算公式。通过比较算例,抗拔力计算公式得到证实,具有实用价值。
From the constitution of anchor system, the influence of the interface strength between bolt and grout medium and between grout medium and soil or rock on of pullout resistance of fully grouted anchor was investigated. Then a formula for pullout resistance of fully grouted anchor was derived by considering the plastic zone developed on the interface between grout medium and soil or rock. Some conclusions were obtained in the practical application of the formula.
