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,影响了建筑物的安全使用。文中首先分析了地下工程开挖引起建筑物破坏的力学机理,然后用数值模拟研究分析了由于地下工程开挖在建筑物内部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 caused by underground excavations brings adverse influence surround buildings. In this paper, causes of land subsidence are analyzed. Then, cracks and addictive stresses occurring in the structure of high-rise building from land subsidence are numerically calculated. Finally, measures to reinforce the building structure and decrease land subsidence for the safe behavior of buildings are suggested.
