谈斜支撑在成都东郊基坑支护工程中的运用

On diagonal ligament in foundation support project at East Suburb in Chengdu

通过工程实例,介绍了斜支撑支护体系在成都东郊膨胀性粘土地区基坑支护中的运用,指出由于斜支撑刚度大,可靠度高,可大大减少原支护结构中支护桩的嵌固深度,经济性好,可作为该区域较可靠的一种基坑支护方式。

Combining with engineering examples, the paper introduces the application of the diagonal ligament support system in the foundation pit support at the expansive clay area of Dongjiao of Chengdu, and points out the embedded depth of the support pile can be reduced of the formal support structures with the money-saving effect because of large stiffness and higher reliability of the diagonal ligament, so it provides the reliable foundation pit support form in the region.
