 Civil Engineering Research Journal- Juniper Publishers   Abstract Purpose:  Post-disaster housing reconstruction projects are considered complex and complicated projects in nature which in turn represents many challenges because it is unlike routine construction. Clarifying failure factors facing organizations in post-disaster housing reconstruction is essential to ensure success in reconstruction projects. The study aimed to identify and rank the main failure factors that organizations experienced in post-disaster housing reconstruction projects. Design/methodology/approach:  The quantitative approach was adopted; a structured questionnaire is used to collect the data from a purposive sample. 115 copies questionnaires were distributed to experts’ engineers who worked in the previous post-disaster housing reconstruction projects in Gaza Strip and 105 copies were received from the respondents with a response rate = 91.30%. The collected data were analyzed with the Statistical Package f

 Civil Engineering Research Journal- Juniper Publishers Abstract In the process of tunnel construction in karst area, unexpected geological disasters such as water inrush and mud inrush are often encountered, which brings great disaster and incalculable economic loss to the construction safety, in order to ensure the smooth operation of tunnel construction and the safety of the late construction of the tunnel, it is necessary to select and remove the reasonable construction plan. In the course of highway tunnel construction in a mountainous area, after entering the rainy season, with the tunnel digging into the melting section of the Xeon Rock, the tunnel water inrush and seepage are obviously aggravated, and after the natural drainage of the original design is serious, the reason of the water accumulation in the hole is analyzed, three kinds of water treatment schemes in the hole are formulated, The best treatment scheme was eventually selected. It provides reference for similar karst
