摘要
地下工程开挖引起的附近地面沉降会给建筑物带来不利的影响,建筑物上部结构和基础作为一个整体共同变形。首先分析了高层建筑上部结构与地基基础共同作用的力学机理,然后采用数值模拟研究分析了在地下洞室开挖的影响下,对高层建筑的作用及在建筑物上部结构与基础中产生的附加应力和裂缝,最后提出了减少地下工程开挖对建筑影响的相应措施。
The land subsidence rose from underground excavations brings adverse influence for surround buildings. Superstructure and foundation will interact as a whole under the influence. In this paper, mechanism of interaction is analyzed. Then, interaction and cracks and addictive stresses occurring in the structure of high-rise building from land subsidence are numerically analyzed. Finally, measures to reinforce the building structure and decrease land subsidence for the safe behavior of buildings are suggested.
