1、山地建筑地下室外墙设计理论与应用研究        【中文摘要】随着高层建筑的蓬勃发展,各种可用土地资源不断得到开发利用,山地建筑也日益增多。对于山地城市,如西部多山地丘陵的省市,其地形特征对山地建筑的选址、设计和施工都有较大影响。而作为山地建筑设计的重要原则就是节约用地,充分利用山地特征。因此山地建筑地下室的开发和利用就显得尤为重要。但由于山地建筑场地环境极为复杂,其地下室设计和施工面临的工程技术题目也日益增多。由于山地建筑场地平整时土方工程量大且易形成很多高陡人工边坡,山地建筑地下室外墙支护结构设计计算理论和应

2、用的研究就成为山地建筑设计的一项重要内容。为此,本文主要对山地建筑地下室外墙支护结构的具体设计计算方法展开研究。本文首先深进分析了山地建筑地下室外墙土压力的特点,对其常规计算方法进行了相关阐述,并在此基础上引进广义库仑土压力计算理论,结合山地建筑地下室外墙的特点改进了简化广义库仑土压力计算方法,进而分析考虑超载、地下水等影响因素时山地建筑地下室外墙土压力分布特点,获得了一些有益的结论。其次,针对山地建筑地下室外墙结构与一般外墙不同的特点,对其计算模型、计算荷载、荷载组合形式及其内力分析和截面设计进行了研究和探讨,同时考虑山地建筑地下室外墙必须与支挡结构共同工作特点,对山地建筑支挡结构选型及其设

3、计计算方法和构造措施做相关阐述,并重点先容了工程中常用的悬臂式混凝土挡墙的设计计算方法。在此基础上,根据山地建筑地下室外墙的工程特点以及目前实际工程中的地下室外墙设计现状,提出一种兼作地下室外墙的支挡结构-外墙支护体系,并对其计算方法进行了探讨,同时对其设计计算的影响因素进行了分析。最后,以某实际工程施工期间及竣工后土压力和位移等参数的监测结果的分析验证支挡结构-外墙体系的可行性与公道性,并采用有限元分析程序SATWE对其进行计算分析,从数值分析的角度验证支挡结构-外墙体系设计计算方法的正确性和公道性。');【Abstract】 Along with high-rise constru
