玻纤土工格栅加筋挡土的基本结构

        玻纤土工格栅加筋挡土墙以其适应性强、占地少、施工方便、抗震好、造价低等一系列的优点而得到广泛的采用。近年来，国内外很多学者针对在加筋挡土墙的主要结构型式及其作用机理方面开展了深人的研究,并取得了一定的成果。

Glass fiber geogrid reinforced retaining wall is widely used because of its strong adaptability, less land occupation, convenient construction, good earthquake resistance and low cost. In recent years, many scholars at home and abroad have carried out in-depth research on the main structural types and mechanism of reinforced retaining walls, and made some achievements.

        玻纤土工格栅加筋挡土墙一 一般是由填土和玻纤土工格栅以及竖直的墙面板三部分组成的整体复合性的挡土结构，其主要填筑过程包括三个步骤。**先在需要挡土的坚实地基上建立墙面的基础部分,然后作为筋材的玻纤土工格栅，在此基础上填筑土体并按照规范要求碾压密实,然后按照这个顺序逐层填筑下去，直到挡墙的高度达到设计要求为止。

Glass fiber geogrid reinforced retaining wall is generally composed of three parts: fill, glass fiber geogrid and vertical wall panel. Its main filling process includes three steps. First, the foundation part of the wall surface shall be built on the solid foundation requiring retaining, and then the glass fiber geogrid shall be used as the reinforcement material. On this basis, the soil shall be filled and compacted according to the specification requirements, and then filled layer by layer according to this order until the height of the retaining wall meets the design requirements.

        在玻纤土工格栅加筋挡土墙的结构体系中，土体在自重和外荷载的作用下将产生侧向变形的趋势，而t工格栅的加入将在这一荷载的作用下与土体材料之间产生相互的摩擦作用5-制。玻纤土工格栅不仅将容易变形的土体分隔成了上下两个部分，而且限制了土体材料的侧向变形,增强了土体的整体性，从而提高了土体的抗剪强度改良了土的力学特性。

In the structure system of glass fiber geogrid reinforced retaining wall, the soil will produce the tendency of lateral deformation under the action of self weight and external load, and the addition of T-grid will produce the mutual friction effect with the soil material under the action of this load. Glass fiber geogrid not only separates the easily deformed soil into upper and lower parts, but also limits the lateral deformation of the soil material, enhances the integrity of the soil, thus improves the shear strength of the soil and improves the mechanical properties of the soil.

        通过玻纤土工格栅加筋材料形成挡土墙的方法，不仅保持了土体材料的完整性，而且很好的约束了挡墙内侧土体的侧向变形，良好的改善了挡墙后面土体的整体应力场和位移场的分布规律，均化了应力分布以及土体的不均匀沉降。

The method of forming retaining wall with glass fiber geogrid reinforced material not only keeps the integrity of soil material, but also restricts the lateral deformation of the soil inside the retaining wall, improves the distribution law of the overall stress field and displacement field of the soil behind the retaining wall, and homogenizes the stress distribution and differential settlement of the soil.

        就细部构造而言，玻纤土工格栅加筋挡土墙主要由面板.基础、填料、玻纤土工格栅以及帽石五个部分组成。其中，面板材料-般为钢筋混凝土面板.其作用主要是挡住墙后的回填土料，同时起到对墙体的装饰作用，并且能够将墙体的拉力传递给墙后的加筋材料。

In terms of detail structure, the glass fiber geogrid reinforced retaining wall is mainly composed of five parts: panel, foundation, filler, glass fiber geogrid and cap stone. Among them, the panel material is generally reinforced concrete panel, which is mainly used to block the backfill soil behind the wall, and plays a decorative role on the wall, and can transfer the tension of the wall to the reinforced material behind the wall.

        基础部位主要分为面板下的条形基础以及加筋体下的基础部分，条形基础的主要作用是便于安置墙体的面板部分，起到对上层面板的支撑和定位的作用，条形基础以及墙体下的基础都应该满足地基承载力的基本要求。回填料部分，应该选择容易压实且与加筋材料之间有足够的摩擦力的材料作为回填土料。玻纤土工格栅材料一般选择抗拉性能比较好，抗拉强度高的玻纤土工格栅材料作为挡墙的加筋材料。帽石部分-般采用现浇混凝土或者浆砌石混凝土预制块或者浆砌石作为玻纤土工格栅加筋挡土墙的压顶或者帽石。

The foundation is mainly divided into the strip foundation under the panel and the foundation under the reinforced body. The main function of the strip foundation is to facilitate the placement of the panel part of the wall and play the role of supporting and positioning the upper panel. The strip foundation and the foundation under the wall should meet the basic requirements of the foundation bearing capacity. For the backfill part, the materials that are easy to be compacted and have enough friction with the reinforced materials shall be selected as the backfill materials. Generally, the glass fiber geogrid material with good tensile property and high tensile strength is selected as the reinforcement material of retaining wall. In the cap stone part, the cast-in-place concrete or masonry concrete precast block or masonry are generally used as the coping or cap stone of the glass fiber geogrid reinforced retaining wall.
