    摘要
  • 摘要: 通过对不同压力注浆参数下土钉现场抗拉试验,分析了不同土钉长度下注浆量、浆液水灰比等注浆参数对土钉受力性状的影响。分析结果表明,在试验范围内,相同注浆量下,土钉极限抗拉强度随着水泥浆液水灰比的减小而增大。对于单位长度内注浆量较高的短土钉,注浆量越高,浆液水灰比对极限抗拉力变化率的影响越小,反之,在单位长度内注浆量较低的长土钉中,注浆量越高,浆液水灰比对极限抗拉力变化率的影响越大。相同浆液水灰比下,土钉极限抗拉强度随着注浆量的增大而增大。对于单位长度内注浆量较高的短土钉,水灰比越大,注浆量对极限抗拉力变化率的影响越大,反之,在单位长度内注浆量较低的长土钉中,水灰比越大,注浆量对极限抗拉力变化率的影响越小。
    Abstract: Based on the soil-nailing tensile experiments under different pressure grouting parameters, the effect of grouting parameters such as grouting amount and water-cement ratio on bearing capacity of soil nailings with different lengths is analyzed. The results show that, in the experimental range, under the same quantity of grouting, the ultimate tensile strength of soil nailings increases with the decreasing water-cement ratio. Specifically speaking, for the short soil nailings with higher grouting quantity in unit length, the higher the grouting quantity is, the lower the effect of water-cement ratio on the change rate of the ultimate tension is. On the contrary, for the long soil nailings with lower grouting quantity in unit length, the effect of water-cement ratio on the change rate of the ultimate tension is larger while the quantity of grouting is higher. Meanwhile, under the same water-cement ratio, the maximum tensile strength of soil nailings increases with the quantity of grouting increases. Here, for the short soil nailings with higher grouting quantity in unit length, the higher the water-cement ratio is, the larger the effect of grouting quantity on the change rate of the ultimate tension is. Conversely, for the long soil nailings with lower grouting quantity in unit length, the higher the water-cement ratio is, however, the lower the effect of grouting quantity on the change rate of the ultimate tension is.
