    摘 要:復合型土釘墻可應用于含水豐富的粉細砂、砂卵石地層,亦可應用于厚度小于4m、無臨時自穩能力的淤泥等飽和軟弱地層,并可兼作擋水結構。復合型土釘墻中的帷幕體除了起著擋水、載水作用外,另外一個重要作用是固化飽和軟弱地層,在支護工作面形成一道“屏障”,保證支護工作面不出現流沙或淤泥流動等地層損失現象。結合某深基坑工程案例,介紹了土釘支護技術的具體應用情況。 Abstract: Composite soil-nailing wall can be applied in water-rich fine sand stratum、cobble and sand stratum, and can also be used in soft soil layer which is less than 4m thickness, non-provisional self-stability silt and other saturated soft soil layers, and it can also be applied to water-retaining structure. Curtains of composite soil-nailing wall not only have the role of water-retaining and water-loading, but also have the role of curing saturated soft soil layer, which can form a barrier in supporting working face to ensure not appearing layer lose phenomenon such as shifting sand or flowing silt. Combining with a deep foundation pit project, the specific application situations of soil-nailing supporting technique are introduced.

    摘 要:為提高高強、超高強混凝土的韌性和抗開裂性能,采用復合超疊加技術在配制出抗壓強度110MPa以上基體混凝土的基礎上,分別配制出了鋼纖維增強超高強混凝土、PVA纖維增強高強混凝土,同時對不同體積摻量的兩種纖維混凝土進行了立方體抗壓、軸向抗壓、劈裂抗拉、抗彎性能和彈性模量等力學性能的測試,并對超高強纖維混凝土進行了彎曲韌性的試驗研究。結果表明,鋼纖維對高強混凝土的立方體抗壓強度、軸心抗壓強度有一定的增強作用,PVA纖維卻降低了高強混凝土的立方體抗壓強度、軸心抗壓強度。兩種纖維都能明顯改善基體混凝土的劈裂抗拉強度、抗彎強度及彎曲韌性。對此種超高強基體混凝土,鋼纖維的增強增韌效果明顯好于PVA纖維。 Abstract:To improve toughness and crack resistance of high-strength and ultra high-strength concrete, based on preparing normal concretes with over 110MPa compressive strength by the multiple super-overlapping technology, steel fiber-reinforced ultra high-strength concrete and PVA fiber-reinforced high-strength concrete are separately prepared. At the same time, the mechanical properties of cubic compressive strength, axial compressive strength, splitting tensile strength, bending behavior and elastic modulus of two kinds of fiber reinforced concrete with different volume dosage are tested. And flexural toughness of ultra high-strength fiber reinforced concrete is researched. The results indicate that cubic compressive strength and axial compressive strength of high strength concrete reinforced by steel fiber have the definite enhancement, but PVA fiber can decrease the cubic compressive strength and axial compressive strength of high strength concrete. Two kinds of fiber can obviously improve splitting tensile strength, bending behavior and flexural toughness of normal concrete. For this kind of ultra high-strength normal concrete, the effects of steel fiber on enhanced intensity and toughness are better than the effects of PVA fiber.
