style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 1．使得水流或波浪直接作用于布排的面積大大減小，只是孔隙部分，土工布這部分水流或波浪也經過護面(底)材料的孔隙周邊摩擦進行了消能； </span><br /> <span style="line-height:2.5;font-family:Microsoft

style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 土工布的透水性：</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 1、透水性好在纖維間有空隙，故有良好的滲水性能。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 2、施工方便，由于材質輕、柔，故運送、鋪設、施工方便。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 3、強力高，由于使用塑料纖維，在干濕狀態下都能保持充分的強力和伸長。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 4、耐腐蝕，在不同的酸堿度的泥土及水中能長久地耐腐蝕。</span><br /> <span

style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">www.meesuksilver.com</span></a><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">　?、?strong><u><span style="font-size:24px;"><a href="http://www.meesuksilver.com" target="_blank">土工布</a></span></u></strong>保護士的熟粒含量對織物保土性設計準則oM石4dD的保土性系數4起著控制作用c：憨粒含量多，4值就應偏大一些；熟粒含量少，4值就應偏小一些。這是因為惑粒含量較多的土壤顆粒之間具有較強的豹結力，甚至成團狀結構，土工布通過細粒土土工織物反應的性能室內研究結果也證實了這一點。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">　?、谠诜雷o工程中，水流含沙量也影響織物保土性設計難則oM事4d的保土性常數4 值，c含沙量大，4值也大些；含沙量少，4值就應小些。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> </span><span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">③土工布合理地覆蓋壓載使得土工織物與被保護土緊密接觸是防護工程中織造布保土性新準則提出的前提c因為合理地理蓋壓載至少有以下幾方面重要作用： </span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 1．使得水流或波浪直接作用于布排的面積大大減小，只是孔隙部分，土工布這部分水流或波浪也經過護面(底)材料的孔隙周邊摩擦進行了消能； </span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 2．使得土工織物濾層布排與被保護土緊密接觸，從而增強約束土顆粒的能力而不至了發生鼓包現象； </span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 3．防止土工織物受日照而老化。 </span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 土工布的透水性：</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 1、透水性好在纖維間有空隙，故有良好的滲水性能。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 2、施工方便，由于材質輕、柔，故運送、鋪設、施工方便。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 3、強力高，由于使用塑料纖維，在干濕狀態下都能保持充分的強力和伸長。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> 4、耐腐蝕，在不同的酸堿度的泥土及水中能長久地耐腐蝕。</span><br /> <span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;"> </span><span style="line-height:2.5;font-family:Microsoft YaHei;font-size:18px;">由于土工布有良好的透水性和保土性，在工程材料中是不可缺少的部分，了解詳情點擊</span><a
