e they are less susceptible to vandalism and often do not require select backfill, typically they pete well in costs where the wall is short (20 to 50m in length) and not very high (say, under 4m). they are also widely used for basement walls and the like in buildings. The mechanically reinforced earth wall of uses the principle of placing reinforcing into the backfill using devices such as metal strips and rods, geotextile strips and sheets and grids, or wire grids. There is little conceptual difference in reinforcing soil or concrete masses——reinforcement carries the tension stresses developed by the applied loads for either material. Bond stresses resist rebar pullout in concrete。 鋼筋混凝土懸臂墻仍相當(dāng)普遍在城市地區(qū),因?yàn)樗麄兪遣蝗菀资艿狡茐?,往往不需要選擇回填,通常他們在成本競爭的墻很短( 20 米長)并不是很高(比如說,下)。 ①填土 —— 通常會選擇小于 15%通過 200 號篩的顆粒材料。 暴露的增援部隊通常是噴混凝土砂漿或噴漿(材料類似于迫擊炮)在電梯生產(chǎn)厚度為 150 至 200 毫 米。無側(cè)向土壓力左進(jìn)行的墻面材料,他們可以做得很薄的和靈活的主要功能的版本控制和外觀。網(wǎng)格式鋼筋加強(qiáng)土壤通過結(jié)合摩擦和被動壓力抗拔力。然而,盡管這長期的使用中,法國建筑師 H.維達(dá)爾能夠獲得的專利(約 20 世紀(jì) 60 年代中期)的一般配置圖 231,這是他被稱為“加筋土”。 ③懸臂 —— 混凝土或鋼板樁 ④錨 —— 板樁與加筋土的某些配置。Retaining wall Retaining walls are used to prevent retained material
