复合地基区岩溶土洞的稳定性分析与加固技术

土洞塌陷和变形是威胁覆盖型岩溶区建筑物安全和正常使用的典型地质灾害,高速铁路因沉降标准高,对覆盖土层多采用了CFG桩、旋喷桩、搅拌桩等复合地基加固,对土洞的形成及发展起到了相当大的抑制作用。文中研究分析了复合地基加固条件下的土洞稳定性,以及土洞塌陷至路基基底时对垫层网结构的变形与拉力变化情况。提出了根据岩溶地基土洞塌陷的可能性进行分区,结合理论计算成果,合理确定岩溶地基加固措施的有关建议。     

Mapped Displacement Discontinuity Method: Numerical Implementation and Analysis for Crack Problems

The displacement discontinuity method (DDM) is a kind of boundary element method aiming at modeling two-dimensional linear elastic crack problems. The singularity around the crack tip prevents the DDM from optimally converging when the basis functions are polynomials of first order or higher. To overcome this issue, enlightened by the mapped finite element method (FEM) proposed in Ref. [13], we present an optimally convergent mapped DDM in this work, called the mapped DDM (MDDM). It is essentially based on approximating a much smoother function obtained by reformulating the problem with an appropriate auxiliary map. Two numerical examples of crack problems are presented in comparison with the conventional DDM. The results show that the proposed method improves the accuracy of the DDM; moreover, it yields an optimal convergence rate for quadratic interpolating polynomials.     

Application Research of Genetic Algorithm on the Whole-Spacecraft Vibration Isolation System

The objective of the whole-spacecraft vibration isolation (WSVI) system is to reduce the launch-induced dynamic loads and the quality control cost of the satellite and its components, and to increase the launch reliability by insertion of isolators between the satellite and the launch vehicle. A niche hybrid genetic algorithm (NHGA) is proposed to optimize stiffness and damping of the isolators. Through the comparison of the frequency response analysis results, it shows that the optimized WSVI system more effectively reduces spacecraft axial / lateral response due to the broadband structure-born launch environment. At the same time, the case of the whole-spacecraft vibration isolation optimization design demonstrates the efficiency and validity of the genetic algorithm.
