【摘要】：為了明確生物能源副產(chǎn)品木質(zhì)素在道路工程土體加固領(lǐng)域的研究現(xiàn)狀,根據(jù)國內(nèi)外大量文獻(xiàn)中有關(guān)木質(zhì)素加固土體的相關(guān)報(bào)道,對木質(zhì)素與土體之間的相互作用機(jī)理進(jìn)行了綜述,并對比了各種固化機(jī)理模型,總結(jié)了國內(nèi)外評價(jià)木質(zhì)素加固土性能的方法和相關(guān)典型室內(nèi)試驗(yàn)結(jié)果,同時(shí)論述了木質(zhì)素加固土的抗侵蝕特性,歸納了木質(zhì)素加固土抗侵蝕特性的室內(nèi)試驗(yàn)方法。分析結(jié)果表明:生物能源副產(chǎn)品木質(zhì)素是一種具有工程應(yīng)用前景的土體固化添加劑,具有環(huán)境友好、成本低廉等特點(diǎn);木質(zhì)素加固土在力學(xué)特性和抗侵蝕特性等方面均表現(xiàn)優(yōu)越;木質(zhì)素與土體的相互作用機(jī)理和加固土的耐久性能仍需要進(jìn)一步試驗(yàn)研究與驗(yàn)證;關(guān)于木質(zhì)素加固土的現(xiàn)場施工工藝和效果評價(jià)尚缺少相關(guān)研究,有待開展此方面的研究工作。
[Abstract]:In order to clarify the research status of lignin as a by-product of bioenergy in the field of soil reinforcement in road engineering, according to a large number of literatures at home and abroad about lignin soil reinforcement related reports. The interaction mechanism between lignin and soil is summarized, and various curing mechanism models are compared. The methods to evaluate the performance of lignin reinforced soil at home and abroad and the results of relevant typical laboratory tests are summarized. At the same time, the anti-erosion characteristics of lignin reinforced soil are discussed, and the indoor test methods of the anti-erosion characteristics of lignin reinforced soil are summarized. The results show that lignin, a by-product of bioenergy, is a kind of soil curing additive with engineering application prospect, which has the characteristics of friendly environment and low cost. The mechanism of interaction between lignin and soil and the durability of strengthened soil still need to be further studied and verified. The field construction technology and effect evaluation of lignin reinforced soil are still lack of relevant research, which needs to be carried out.
