强夯法加固地基普遍用于工程中,该方法除难以处理淤泥外,在其它土体的地基处理中均有或广泛采用,该方法也同样广泛用于加固广东地区的花岗岩残积土。根据广东地区的花岗岩残积土的土体性质,结合强夯加固同一工程两个试验区的新堆填花岗岩残积土的试验监测结果,确定与花岗岩残积土性质相适应的强夯施工技术参数,对各强夯施工参数评价方法做了进一步分析并提出新的见解; 通过结合监测和检测的土体物理力学性质指标对加固效果进行了完整的评价,总结出了不同夯击能或不同岩土性质对强夯加固花岗岩残积土效果的影响。 相似文献

Despite the large size of most communication and transportation systems, there are short paths between nodes in these networks which guarantee the efficient information, data and passenger delivery; furthermore these networks have a surprising tolerance under random errors thanks to their inherent scale-free topology. However, their scale-free topology also makes them fragile under intentional attacks, leaving us a challenge on how to improve the network robustness against intentional attacks without losing their strong tolerance under random errors and high message and passenger delivering capacity. Here we propose two methods (SL method and SH method) to enhance scale-free network's tolerance under attack in different conditions. 相似文献
