A Simplified Calculation Method for Spatial Effect In Large-Long-Deep Foundation Pit and its Analysis Mingfeng Leia, Limin Pengb, Chenghua Shic, Yunliang Zhangd and Wenhua Lie School of Civil Engineering and Architecture,Central South University,Changsha 410075,China amingfenglei@yahoo.com.cn, blmpeng@csu.edu.cn,ccsusch@163.com, dzhangyunliang88@126.com,eLiwenhua78326@163.com Keywords: Large-Long-Deep Foundation Pit; Spatial Effects; Simplified Calculation; Soil Plasticity Upper Bound Theory; Associated Flow Rule; Equivalent Internal Friction Angle; Limit Equilibrium Analysis Method Abstract.
Amount of engineering practice indicates that the earth pressure and displacement on central wall are bigger than them on a certain range of end wall in deep foundation pit, which illustrate that the notable spatial effect exists on the end wall, and the development of earth pressure and displacement are inhabited.
l The main influence range of spatial effect lies on two ends in foundation pit, approximately 1/4 of foundation pit length, furthermore, the more notable, the nearer the ends, in that, during practice designing, support structure can be weaker at the ends for saving engineering investment.。
So, in order to full use the spatial effect and saving the engineering investment, it required to select irrespective short excavating boundary during design and construction process.

Analyzing on Bearing Performance Influence Factors of Step Cross-Section Pipe Pile Liu Jie1,a,Huang Fu-an1,b,Yang Qing-guang1,c, Cui Bin1,d 1 College of Civil Engineering, Hunan University of Technology, Zhuzhou, Hunan 412007, China a2860557969@qq.com, b40721799@qq.com, cyqg1210@126.com, d602188839@qq.com Keywords: Step cross-section pipe pile;Bearing capacity; Interaction;Finite difference model.
There was also a filling process of the pile lateral convex rib, and increased the complexity of the construction process; At the same time, added the convex rib of the surface of the pipe pile also increased the difficulty in production, these factors may be the reasons why the new type of ribbed prestressed pipe pile and bamboo pile were not widespread in the engineering application.
It has important theoretical significance and engineering application prospects.

The opinions in this paper are based on visual observations and engineering judgment, rather than quantitative analysis.
Vulnerability Indicators These findings from field observations suggest the possibility of a simple set of vulnerability indicators to form a qualitative index for use by owners, engineers, and building authorities.
The engineer should prioritize interventions based on relative vulnerability in the context of extrinsic risk.
