Unilateral soil-retaining wall applied to slope building and construction method of unilateral soil-retaining wall

LI CHENG

The invention discloses a unilateral soil-retaining wall applied to a slope building and a construction method of the unilateral soil-retaining wall. A soil-retaining wall foundation of the soil-retaining wall is constructed while a foundation of a main body structure is constructed, then the main body structure is constructed to a roof of a hanging layer/a top plate of a basement, and after an isolating layer is arranged on the soil side (the side close to the soil-retaining wall) of frame columns and a side frame beam of the hanging layer/the basement, the soil-retaining wall is constructedfinally, that is, a side wall is isolated from the frame columns and the side frame beam of the hanging layer/the basement of the building main body structure by the isolating layer. Therefore, it isnot needed to additionally arrange a shear wall on the other side of the main body structure, so that the construction cost is saved on the premise of meeting the functions of the building. Moreover,during structural calculation, it is not needed to consider adverse effect that torsional displacement is generated to the main body structure as a result of rigidity of the soil-retaining wall, thatis, the building main body structure can bear earthquake action freely in either the longitudinal direction of the soil-retaining wall or the direction separated from the soil-retaining wall.

本发明公开了一种应用于坡地建筑的单侧挡土的挡土墙及其施工方法，其通过在施工主体结构的基础时，同时施工该挡土墙的挡墙基础，然后再施工主体结构至吊层屋面/地下室顶板，然后在该吊层/地下室的框架柱和边框梁的临土侧(即靠近挡土墙的一侧)设置隔离层后，最后施工挡土墙，即通过该隔离层将该侧壁与建筑主体结构吊层/地下室的框架柱和边框梁隔开，因此，不需要在主体结构的另一侧增设剪力墙，从而在满足建筑功能的情况下节约了建造成本，并且，在进行结构计算时，无需考虑挡土墙刚度对主体结构产生扭转位移的不利影响，即该建筑主体结构无论是在沿挡土墙纵向，还是在脱离挡土墙方向都可以自由承受地震作用。
