摘要
为更好的优化钢支撑轴力伺服系统对基坑及邻近隧道的控制效果,文中通过文献综述法从实测分析、数值模拟、理论研究3个方面对伺服钢支撑在基坑中的应用进行分析,结果分析表明,对钢支撑轴力伺服系统的研究内容主要集中在控制变形效果、对相邻支撑的作用、支撑布置方式及轴力加载等。同时,提出了伺服钢支撑对邻近隧道纠偏防治的控制机理,综合现有研究得出钢支撑轴力伺服系统在现阶段应用过程的不足之处,对今后伺服钢支撑的研究方向提供参考。
In order to better optimize the control effect of steel braced axial force servo system on the foundation pit and adjacent tunnels and put forward guiding suggestions for practical engineering,the application of steel braced servo system in the foundation pit was analyzed from three aspects of measured analysis,numerical simulation and theoretical research in literatures review. The results show that the research contents of the axial force servo system of steel braces are mainly focused on the deformation control, adjacent braces, the support arrangement, and the axial force loading. At the same time, the control mechanism of servo steel braces for the correction and prevention of adjacent tunnels is proposed. Based on the existing studies, the shortcomings of the steel braces axial force servo system in the current application process are concluded. Finally, the personal views and prospects of the future research direction of servo steel braces are put forward.
