当前,随着我国经济发展速度的不断加快,以及城市化进程的不断深入,使得建筑行业得到了较为快速的发展,越来越多的高层建筑如雨后春笋般拔地而起。而随着高层建筑的增多,基坑工程的数量和深度也随之增加,这便使得对于地下结构施工以及高层建筑周围的环境设施的安全性,有了更高的要求,因此,在进行深基坑支护作业中,要明确选取合理的设计方案,并进行深基坑支护的优化设计。本文简要阐述了深基坑支护方案选取的要点,并进一步作出了深基坑支护方案的优化选择,随后,对深基坑支护的优化设计进行了详细的分析,并有针对性的进行了方案设计中的具体内容优化研究,旨在为确保深基坑支护作业的合理完成、为确保高层建筑地上部分的有效过度和衔接,做出自己应有的贡献。
At present, with the continuous acceleration of the economic development in our country and the deepening of the urbanization process, the construction industry has enjoyed rapid development. More and more high-rise buildings have mushroomed. With the increase of high-rise buildings, the number and depth of foundation pit projects also increase, which makes the requirements for the safety of underground structures and the environmental facilities around high-rise buildings higher. Therefore, In the excavation support operation, it is necessary to select a reasonable design scheme clearly and optimize the design of deep foundation pit support. In this paper, the essentials of the selection of the deep foundation pit support scheme are briefly described, and the optimal choice of the deep foundation pit support scheme is further made. Then, the optimal design of the deep foundation pit support is analyzed in detail and targeted The specific content optimization research in program design is carried out. The purpose of this project is to make its due contribution in order to ensure the rational completion of the deep foundation pit supporting work and ensure the effective over-connection and connection of the above-ground part of the high-rise building.
