【摘要】：在建筑工程里,基坑工程是施工过程中重要的组成部分。作为建筑的基础施工部分,基坑的开挖与支护[1]显得尤为至关重要。同时,随着我国的快速发展,在一些一线城市中,以深圳为首,各种高楼大厦像雨后春笋般以闪电般的速度矗立在城市的中心。伴随着建筑高度[2]的提高,从而给基坑的开挖与支护带来了更加艰难的挑战,这对于建筑以后的稳定起到了基础的作用。在经济发展的同时,人们纷纷涌向了大城市,导致一线城市人口剧增,进一步使城市的面积变得不够用起来。为了节约空间的使用,我们不得不把目光放在地下空间和高层建筑里,比如地下车库、地铁、复合式办公楼以及高达几十层的居民住宅。这些建筑工程的快速建设和发展,也导致了基坑工程[3]的大量出现,也在一定程度上加大了我国基坑的实际施工和应用。可以说城市的发展带动了地下空间和高层建筑的发展,进一步带动了基坑程的发展和研究。当代摩玛置业的花园小区位于合肥市蜀山区岳西路边上,中建三局为主要施工方。目前大部分楼栋处于基坑开挖阶段,或正在进行基坑的支护,现场的施工进度满足课题的内容要求。在17#和18#的高层楼施工过程中,我们对施工现场的基坑开挖情况进行研究和记录,以及基坑技护时根据现场的施工环境和周边的地理位置来选择最适合本工程的支护方案。论文的研究和记录结果,对本工程和今后类似的基坑开挖与支护工程,能够提供一定的参考价值。
[Abstract]:In building engineering, foundation pit engineering is an important part of construction process. As the foundation construction part of building, excavation and support of foundation pit. [At the same time, with the rapid development of our country, in some first-tier cities, Shenzhen is the first. All kinds of tall buildings sprang up at lightning speed in the center of the city. With the height of the building. [2] the improvement of the foundation pit excavation and support has brought more difficult challenges, which plays a fundamental role in the stability of the building. At the same time of economic development, people are flocking to the big cities. In order to save space, we have to focus on underground space and high-rise buildings, such as underground garage, subway. The rapid construction and development of complex office buildings and residential buildings up to dozens of storeys have also led to foundation pit works. [3) the emergence of large quantities of foundation pit has also increased the actual construction and application of foundation pit in China to a certain extent. It can be said that the development of the city has driven the development of underground space and high-rise buildings. The development and research of foundation pit is further promoted. The garden district of contemporary MoMA home is located on the side of Yuexi road in Shushan District of Hefei City, and the third Bureau of China Construction is the main constructor. At present, most of the buildings are in the excavation stage of foundation pit. Or is carrying on the foundation pit support, the site construction progress meets the subject content request. In the 17# and 18# high-rise building construction process, we carry on the research and the record to the construction site foundation pit excavation situation. And according to the site construction environment and the surrounding geographical location to select the most suitable support scheme. The research and record of the results of this paper and similar excavation and support works in the future. Can provide certain reference value.
