Abstract: This paper mainly analyzed reason for formation of subsidence on a part of WeiPu highway foundationWeinan to Puchengin the middle of Shaanxi Provinceand discussed integrated reinforcement construction techniqueincluding quicklime pileCGMTand grouting reinforcement. At present time of transportationthis construction technique ensured high quality of foundationimproved the construction progress and saved the cost. Thus, this is an effective method of construction technique.
