预应力混凝土柱的施工技术

Technique of prestress concrete pile construction investigation

偏心受压钢筋混凝土柱,采用预应力技术减小或避免钢筋混凝土柱根部裂缝,通过在钢筋混凝土柱受拉区一侧预先施加一定的力,使钢筋混凝土柱内部受力在新的条件下建立平衡.实践证明:该方法能有效地控制柱截面,解决钢筋混凝土柱偏心受压的根部裂缝问题.

Eccentric reinforce pressed column and root common fissures show the failure of construction quality, the application of prestress technology to reduce or avoid the root fissure problem of reinforced column by transmitting some power to the reinforced column tensile region on one side in advance to make a balance for its internal force under new condition proves effectively in the three-mouth practice in Qingdao accommodation center project.
