【摘要】：本文通過現(xiàn)場(chǎng)試驗(yàn)研究,開發(fā)了一種無砂吹填超軟土真空預(yù)壓快速加固工藝,并通過兩項(xiàng)工程實(shí)例對(duì)該工藝進(jìn)行驗(yàn)證和應(yīng)用。研究認(rèn)為濾管排水板連接,埋入泥下20~30 cm作為真空預(yù)壓抽氣排水通道是可行的;排水板間距對(duì)超軟土真空預(yù)壓加固效果的影響是敏感的。在天津港某工程二次真空預(yù)壓加固的淺層加固中采用56 cm排水板間距,使超軟基迅速加固,形成滿足重型插板機(jī)插板的工作界面,真正實(shí)現(xiàn)二次無砂真空預(yù)壓地基加固。
[Abstract]:This paper through the field tests, the development of a non sand dredger fill ultra soft soil vacuum preloading and rapid reinforcement process, through two engineering examples for validation and application of this technology. The research results indicate that the filter plate is connected with the drainage, buried under mud 20~30 cm as vacuum preloading pumping drainage channel is feasible; the drainage effect plate spacing on the ultra soft soil vacuum preloading effect is sensitive. Using 56 cm drainage plate spacing in the shallow layer of a project of Tianjin port two vacuum preloading reinforcement, the super soft foundation reinforcement rapidly, formed to meet the heavy plate inserting machine work interface, realize two times without sand vacuum preloading Foundation reinforcement.
