道路沉降、开裂？基底处理做好这几步，工程质量稳了！

在现代市政道路(lu)工(gong)(gong)程中，土(tu)工(gong)(gong)布(bu)铺(pu)设(she)是衔接基(ji)底(di)处理(li)与(yu)路(lu)面施工(gong)(gong)的关键环节(jie)，其核(he)心价(jia)值(zhi)在于通过土(tu)工(gong)(gong)布(bu)的隔离、反滤、排水、加筋四(si)大(da)功(gong)能(neng)，优化路(lu)基(ji)受力结构，阻止土(tu)壤颗粒流(liu)失，疏导地下渗水，从而显著提(ti)升路(lu)基(ji)的稳(wen)定(ding)性(xing)、承载力和耐久性(xing)，为道路(lu)长期(qi)安全运行筑牢 “隐形防护网”。土(tu)工(gong)(gong)布(bu)的铺(pu)设(she)质量直接影(ying)响路(lu)基(ji)综合(he)性(xing)能(neng)，需(xu)严(yan)格遵循(xun)规(gui)范(fan)流(liu)程，把控每个施工(gong)(gong)细节(jie)。
