    • A connection system for stabilizing an earth wall is disclosed. The system may include a geosynthetic loop assembly partially embedded within a concrete panel. The geosynthetic loop assembly may include a plurality of spaced apart geosynthetic loops that may be connected by at least one transverse geosynthetic strip. The geosynthetic loops are partially embedded within the concrete panel and partially extending from a front face of the concrete panel in generally aligned relationship. The system may also include a geosynthetic reinforcement web including a plurality of longitudinal geosynthetic strips and a plurality of transverse geosynthetic strips. The web may be folded to form a fold and the longitudinal strips adjacent the fold may be positioned adjacent the geosynthetic loops extending from the front face of the concrete panel in aligned relationship to form a passageway. The system may include a locking member disposed in the passageway to engage the geosynthetic loop assembly to the geosynthetic reinforcement web.
    • 公开了一种用于稳定土墙的连接系统。 该系统可以包括部分地嵌入在混凝土面板内的土工合成环组件。 土工合成环组件可以包括多个间隔开的土工合成环,其可以由至少一个横向土工合成带连接。 土工合成环部分地嵌入在混凝土面板内,并且以一般对齐的关系部分地从混凝土面板的前面延伸。 该系统还可以包括包含多个纵向土工合成带和多个横向土工合成带的土工合成加强网。 网可以被折叠以形成折叠,并且邻近折叠的纵向条可以被定位成邻近从对准关系的混凝土面板的前面延伸的土工合成环,以形成通道。 系统可以包括设置在通道中的锁定构件,以将土工合成环组件接合到土工合成加强网。

    • A fatigue resistant gravity based spread footing under heavy multi-axial cyclical loading of a wind tower. The foundation having a central vertical pedestal, a substantially horizontal continuous bottom support slab, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal, ribs and slab forming a continuous monolithic structure. The foundation having a three-dimensional network of post-tensioning elements that keep the structural elements under heavy multi-axial post compression with a specific eccentricity intended to reduce stress amplitudes and deflections and allows the foundation to have a desirable combination of high stiffness and superior fatigue resistance. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

    • A retrofit reinforcing structure addition and method for an existing gravity spread foundation for a wind turbine or the like having a central pedestal and a spread section is provided. The retrofit structure addition includes a collar formed around the pedestal of the spread foundation. The collar is formed by a shape sustaining member, such as a CMP, placed around the pedestal to define an annular ring between the CMP and the pedestal that is filled with cementitious material. Radial bolts extend horizontally through the collar and into the side of the pedestal. Soil and/or rock anchor bolts extend vertically through the collar, the spread portion of the foundation and into the underlying soil and/or rock substrate. The radial and anchor bolts are post-tensioned to ensure that the cementitious material of the collar remains in compression and the bolts are always in static tension, strengthening the original gravity spread foundation and extending the fatigue life thereof.
    • 提供了一种用于具有中心基座和扩展部分的风力涡轮机等的现有重力传播基础的改进加强结构添加和方法。 改造结构添加包括围绕铺展基础的基座形成的衣领。 套环由放置在基座周围的形状维持构件(例如CMP)形成,以在CMP和具有胶结材料的基座之间限定环形环。 径向螺栓水平延伸穿过轴环并进入基座的侧面。 土壤和/或岩石锚定螺栓垂直延伸通过套环,基础的铺展部分并进入下面的土壤和/或岩石基底。 径向和锚固螺栓被后张紧,以确保轴环的胶结材料保持压缩,并且螺栓总是处于静态张力,加强原始重力传播基础并延长其疲劳寿命。
