广场地下车库的结构设计分析
某车库地下三层,局部地下一层,属于超长结构,结构形式为钢筋混凝土框架结构。笔者着重介绍了该结构超长
不设缝的处理措施和抗浮问题的解决办法。对于超长问题,对各种结构构件在温度作用下的内力、应力进行了计算分
析,并结合其受力特点,采取了针对性的措施。由于地下水抗浮设计水位较高,地下三层部分和地下一层局部下沉广场
处存在抗浮问题。地下一层局部采用了增加底板上覆土厚度的办法解决抗浮问题。地下三层部分经比选采用抗拔桩抵
抗水浮力。

The Structural Design of the Underground Garage in a Square
The garage is with three floors underground and one underground in part, belonging to the super#br# structure, the structure is reinforced concrete frame structure. Author of this paper mainly introduces the#br# treatment measures of the super long structure without joints and the solution to the anti floating problem. For the#br# super long problem, the internal force and stress of various structural members under the action of temperature#br# are calculated and analyzed, and combined with its force characteristics, targeted measures are taken. Because of#br# the high level of anti floating design of underground water, the anti floating problem exists in the three parts of the#br# underground and the local subsidence square of the underground layer. The method of increasing the thickness#br# of the soil cover on the ground floor is used to solve the problem of anti floating. By comparing, the three parts of#br# the underground use uplift pile to resist water buoyancy.
