擁壁は、土の埋め戻しによって引き起こされる横方向の力に抵抗するために使用される便利な構造です。. 使用できる擁壁の設計にはさまざまな種類があります, 構造またはクライアントのニーズに応じて. の種類 擁壁の設計 一般に、負荷に抵抗する方法によって定義され、それぞれに独自の長所と短所があります. 記事上で, we will walk you through 4 types of retaining walls with illustrative diagrams:

Parts of a Retaining Wall

Throughout the article we will be referring to various parts of the retaining wall model, it is useful to first explore the various parts of a retaining wall. The following diagram is taken from the 3D model of SkyCiv’s 擁壁計算機:

今, let’s explore the following types of retaining walls!

Gravity Retaining Wall

Gravity Retaining Walls predominately resist lateral earth pressure (from soil backfill known as active soil) as well as the gravity weight of the structure. There are generally some reactive (upward) forces can be caused from passive soil pressure and hydrostatic pressures caused by water tables. Essentially, the weight of the gravity wall will resist the structure from overturning and sliding. It’s a fairly shallow retaining wall and are generally limited to a few metres, as there are no embedded piles or anchors to support the weight of the active soil.

Materials used in gravity retaining walls is generally stone, concrete and brick masonry. They often feature a ‘batteredor tapered profile, where the base is thicker than the top. This provides additional strength and stability at the base where it is most needed.

Cantilever Retaining Wall

Cantilever Retaining Walls are pretty similar to Gravity Retaining Walls, however they include an additional base component that provides additional restraint against overturning and sliding given this additional concrete. この形状は、積極的な力に抵抗するのにより効果的です, 有効な力の重みが垂直方向の抵抗を提供するため (重力) 転倒や滑りに抵抗する – そのため、一般的に使用できるコンクリートは少なくなります.

名前が示すように, 固定された擁壁は、通常、アンカーを介して土壌へのアクティブな土壌圧力に抵抗します。, 岩または他の抵抗材料. これらのアンカーは、転倒や滑りに抵抗するために必要な力を提供します. Since the anchors are loaded axially, they can withstand higher loads and are a pretty efficient use of materialparticularly as the concrete stem generally won’t need to be as thick. They are also extremely strong designs and more resistant against higher forces where there is less room to work with; typically why you see them used in construction sites where adjacent buildings is a concern.

Sheet Pile Retaining Walls

Sheet piles with a corrugated shape (to increase the bending capacity of the sheet) can also be used to retain the active pressure in retaining walls. They are driven into the soil using a rig and provide additional lateral restraint as it is piled deep into the soil. These types of retaining walls are often used as barriers for groundwater flow and in car parks and are beneficial in areas that don’t have a lot of space for wide barriers.
