为探究循环动荷载下,孔隙尺寸对饱和土地基动力特性的影响,利用虚位移原理及Newmark积分法对非局部Biot模型进行了空间及时间离散,并采用有限单元法编制了循环荷载下饱和土地基动力响应的计算程序.将该程序计算得到的饱和土一维固结结果和二维单相弹性地基的动力响应结果与已有文献对比,验证了该程序的正确性.研究了循环荷载下孔隙尺寸效应对一维饱和地基,二维饱和地基及饱和路基动力特性的影响.结果表明:荷载频率较高时,随着非局部参数的增加,饱和土地基的动力响应明显滞后,孔隙尺寸效应对饱和土地基动力响应的影响明显,即荷载频率较高时,孔隙尺寸效应不可忽略.

作者： Xiang-Qun Fu Hong-wei Li jian-Hong Shi Tan Li Wan-Su Bao Henan Key Laboratory of Quantum Information and Cryptography Information Engineering University Synergetic Innovation Center of Quantum Information and Quantum Physics University of Science and Technology of China

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

为快速准确地评估纵向压力和加固钢板对盾构隧道力学性能的影响,基于隧道衬砌接缝面建立考虑纵向压力、弯矩和加固钢板耦合作用下的应力平衡方程,推导出了隧道力学性能的解析解。通过与经典抗弯刚度理论和数值模拟的计算结果对比,验证了该方法的可靠性。研究表明:隧道中性轴随纵向压力、加固钢板厚度和弹性模量增加而减小;隧道抗弯刚度随弯矩增大而减小(最大和最小隧道抗弯刚度与弯矩大小无关),与纵向压力呈S曲线正相关,与加固钢板厚度和弹性模量呈非线性正相关。有加固钢板的隧道抗弯刚度是无加固钢板的6.58倍;弯矩承载力与纵向压力、加固钢板厚度和弹性模量呈非线性正相关;衬砌接缝张开量与纵向压力、加固钢板厚度和弹性模量呈非线性反相关,与弯矩呈非线性正相关。该计算方法解析地诠释了纵向压力与加固钢板对盾构隧道力学性能的影响机制。
