style="text-indent:25px">耐久性影響鋼材耐久性的因素很多。首先是鋼材的耐腐蝕性差，必須采取防護(hù)措施，防止鋼材腐蝕生銹。防護(hù)措施有：定期對(duì)鋼材油漆維護(hù)，采用鍍鋅鋼材，在有酸，堿，鹽等強(qiáng)腐蝕介質(zhì)條件下，采用特殊防護(hù)措施，如海洋平臺(tái)結(jié)構(gòu)采用“陽(yáng)極保護(hù)”措施防止導(dǎo)管架腐蝕，在導(dǎo)管架上固定上鋅錠，海水電解質(zhì)會(huì)自動(dòng)先腐蝕鋅錠，從而達(dá)到保護(hù)鋼導(dǎo)管架的功能。其次由于鋼材在高溫和長(zhǎng)期荷載作用下，其破壞強(qiáng)度比短期強(qiáng)度降低較多，故對(duì)長(zhǎng)期高溫作用下的鋼材，要測(cè)定持久強(qiáng)度。鋼材隨時(shí)間推移會(huì)自動(dòng)變硬、變脆、即“時(shí)效”現(xiàn)象。對(duì)低溫荷載作用下的鋼材要檢驗(yàn)其沖擊韌性</p><p
