The study of unsaturated slope stability is one of issues in geotechnical engineering.
Although there is a series of simplified assumptions in the mechanics mechanism of the slice method, in most cases, its analyses results also can be close to the actual results, so it is widely used in the engineering practice.

A Residential Building Crack Test and Construction Safety Assessment Luo Jugang1, a , Zhang Jinyang2,b and Zhang Qingsong2,c 1Anhui and Huai River Water Resources Research Institute, Bengbu 233000, Anhui, China 2 Anhui Construction Engineering Quality Supervision Test Station, Hefei 230088, Anhui, China a36041396@qq.com b13605523751@139.com 353981653@qq.com Keywords: Cracks, foundation pit construction, side slope stability crack supervision, test safety Abstract.
Therefore, the following works were done such as the spot checks of the building engineering quality were done; the test and analysis were carried out over the cracks development after the foundation pit was backfilled, the influence assessment of the foundation construction under the mutual effects of pilings and anchor rods over the residential building structure was also conducted; finally the recheck calculation and safety evaluation were made over the building structure.
Fig. 1 SW Building Plane Layout The Engineering Quality Test Result The tested masonry mortar compression strength value is 7.2Mpa~13.6 MPa, the masonry mortar compression strength is not significantly different between non crack and crack zones.
In accordance with article 2.6 of “Evaluation Standard of Civil Architecture Reliability” GB 50292~1999, with the test results of verticality examination, upper structure checkup and foundation pit supporting and its later treatment, the overall analysis shows that the foundation engineering carrying force is able to meet the requirements of application, the foundation is not found of unevenness or deformation, and the foundation engineering is on the stable condition.
It means that the engineering overall structure is safe and in conformity with the requirements in terms of safety and vibration resistance in engineering construction period.

Numerical Modelling and Assessment of Excavation Damaged Zone around the Underground Excavations: a Case Study Dengpan Qiao1, a, Zongsheng Zhang1, b,Shuhong Wang2, c, Yabin Zhang2, d 1 Faculty of Land Resources Engineering, Kunming University of Science and Technology, Kunming, 650093, China; 2 School of Resource and Civil Engineering, Northeastern University, Shenyang,110004,China; aqiaodengpan690821@126.com; bqiaodengpan690821@126.com; cshwang@mail.neu.edu.cn; dnerock@mail.neu.edu.cn Keywords: Excavation Damaged Zone; Microseimic Event; Seismic Velocity; AE Events Abstract.
Following an introduction to the engineering geology and mechanical properties of the rock mass in the Jinchuan mine areas, this paper reveals the features of the measured in situ stresses and puts emphasis on an analysis of the mechanism of underground opening and damage induced by the underground mining.
Stress and AE redistribution induced by excavation of underground engineering results in the unloading zone in parts of surrounding rock masses.
Engineering geology and rock mass property of the mine area To protect the highly productive mining system, to ensure overall success of mining, and to prevent the hazard and to ensure mining safety, planning and design in Jinchuan Mine are essential.
From the convenience of presentation, we can find: (1) Beside the engineering geology and rock mechanical properties, the distribution of the virgin stresses is another predominant factor inducing the redistribution of the surrounding rocks on a large scale.
