摘要: [目的] 某山区电厂的净化站布置于江边,源水就地处理后输送至厂区。江边东侧原始地貌为阶梯状斜坡,河谷边缘地形陡峭,净化站的站区场地需要进行场平处理,站区东北侧需要进行挖方,站区的西南侧需要进行填方,需要设置两幅垂直相交的挡土墙。 [方法] 设计分别提出了重力式挡土墙和扶壁式挡土墙两种方案,并对这两种方案从施工和造价角度分别进行了对比,发现都很难满足现场实际施工需求。最后综合两种方案创新地提出转角复合挡土墙方案,很好地解决了现场实施困难等问题。 [结果] 经过方案比选,设计选用了一种新型转角挡土墙,有效减少了基底面积和钢筋用量,就地取材,节约造价,以较小的经济代价完成了高回填边坡的挡墙结构。 [结论] 通过工程实践证明,这种新型转角挡土墙既满足了现场实际使用功能,又节省了工程造价,还方便了施工。Abstract: [Introduction] The purification station of a power plant in a mountainous area is arranged at the edge of the river, and the source water is disposed on site to be transported to the factory. River on the east side of the original landscape for step slope, valley edge steep terrain, cleaning station station site requires a flat handle, same its northeast, the need for excavation, the southwest side of the station need to fill, you need to set up two vertical intersection of retaining wall. [Method] The design was put forward separately two schemes of gravity retaining wall and buttressed retaining wall, the two schemes were compared from the construction and cost point of view, and it was found that they are difficult to meet the actual site construction needs. Finally,comprehensive two schemes innovatively put forward returnable integral compound type retaining wall, it solved the site problems very well. [Result] After scheme comparison, choose a new angle of retaining wall design, effectively reduced the dosage of basal area and reinforced, local materials, saving cost, finished high backfill slope at the smaller economic costs of retaining wall structure. [Conclusion] The engineering practice proves that this new type of corner retaining wall not only satisfies the actual use function of the site, but also saves the cost of the project and facilitates the construction.
