| 8. | The fem results indicated that as to the rough surfaces in sliding contact , the value of the contact pressure was very high which coursed a high value of the heat flow rate , meanwhile the sliding time was not enough for the frictional heat to transfer , thus the highest value of the body temperature occurred just on the sliding surfaces , which possessed a sharp thermal gradient in direction perpendicular to the sliding surface . so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously , thus this change of the contact pressure would affect the temperature distribution in return
对于相对滑动的粗糙表面，因实际接触面积小而导致接触压力很大，这样使得热流密度会很大，同时由于滑动时间很短，热来不及传导，最高温度发生在摩擦表面，在垂直于摩擦面的方向有很大的温度梯度，使得热应力很大，且最大应力发生在表面，同时产生热弹性变形，这种变形使得接触区域内的压力分布发生变化，这种变化又反过来影响了接触区域的温度分布。 |

为此，本论文提出一种新的锚杆计算模型，它将锚杆与周围岩土体间的相互作用作为接触问题考虑，其计算理论比较严谨，能较好地模拟出锚杆的受力状态及锚杆与岩土体间的剪切?滑移作用，即：锚杆?岩土体之间的接触面具有抵抗强度，当接触面上切向应力小于其抵抗强度时，锚杆与岩土体共同变形；达到抵抗强度时则沿切向发生相对滑动。 |
