Abstract


Tunnel construction monitoring and measurement is an important content of modern tunnel construction technology. Actual and accurate tunnel monitoring data information is the key to guide safe tunnel construction. This paper mainly researches how to deal with monitoring data and the analysis and judgment of safe state of adjoining rock. Based on the construction of Xin Jiao ditch of co-using second-line engineering of Xian– Ankang SKS-2, this paper mainly studies the method of data processing.Firstly, this paper researches data error of monitoring data. Deeply analyzing the existing frequently-used data processing methods, this paper finds out the limitations and bad processing effects of these methods. According to the characteristic of tunnel monitoring data error, this paper deeply researches a new method which can better process data. That is, data processing method based on unascertained theory. This paper proposes a modified unascertained data processing method by analyzing the gross error facts which influence data processing. This paper also validates the superiority of the modified unascertained data processing method by the experimental result contrast of the original and new method. And the paper develops a tunnel construction monitoring management software using VB6.0 and Microsoft Access. The data processing method and data forecast function based on unascertained theory have been successfully used in Xin Jiao ditch tunnel project. Experimental results show that the data dependability has been improved by the unascertained data processing method. This practice can provide accurate reference foundation to tunnel construction and reflect changing circumstances of the tunnel more authentic. This paper also show that the accuracy of the tunnel adjoining rock tendency forecast is higher by using the monitoring data which is processed. Thus, the safety of tunnel construction can be guaranteed.
