| 摘 要： | 某工程在护坡桩施工完毕之后,进行挖土施工锚杆期间,出现了杂填土层桩间涌水、涌砂情况,需要对其杂填土层进行基坑加固.经过详细论证,采用注浆加固,再增加锚杆的方法.根据规范计算两段锚杆的锚固参数,进行锚杆试验,从基本试验结果看出锚杆加固设计可满足要求.成功解决了地下水影响基坑导致停工的问题,保证了工程顺利完工.

| Abstract: | A project faces a problem which is water burst and sand boil between the piles on miscellaneous fill soil when digging the soil and settig up anchors after constructing the slop shield piles,and now we need to reinforce its foundation pit on the miscellaneous fill soil.After detailed demonstration,we use the methods of grouting reinforcement and adding anchor.We calculate the two anchoring parameters according to the specification,and do the anchor test,at last we find out the anchor reinforcement design meeting the requirements according to the basic test results.We successfully solve the shutdown problem caused by groundwater influence and ensure the project completed. |
