Exploration and Practice of Innovative Support System of Large-Scale Deep Foundation Pit in Beijing Shenhua Jiao1, 2, a *, Jin’an Wang1, b and Yaming Liu3, c 1 School of Civil and Environmental Engineering, University of Science and Technology Beijing, Beijing 100083, PRC 2 Beijing Modern Jinyu Construction Co., Ltd., Beijing 100102, PRC 3 Ove Arup & Partners Hong Kong Ltd., Hong Kong, PRC a jiaosh98@163.com, b wja@ustb.edu.cn, c alex.liu@arup.com Keywords: Foundation pit engineering, Support design, Waterproof curtain, Monitoring, Back analysis Abstract: Foundation pit engineering is a critical part during the development process of underground space.
In recent years, numerous failures of foundation pits were reported due to the leakages of freshwater pipes, sewage pipes and heating supply pipes. 4) Increasing environmental protection awareness of people is mainly embodied in: protection of water resources, energy-saving and environment-friendly of construction materials; higher standards for dust and noise control during construction; concept of green project which is recognized more and more.
On the one hand, heavy machines or equipments used for construction may not be allowed to enter sites via the current transportation system; on the other hand, construction materials may always be hindered to sites due to the traffic congestions or temporary traffic control of Beijing.

Influence of a limited efficiency of vacancy sinks/sources at the interfaces on the intermediate phase layergrowth kinetics Model description We will consider an isothermal annealing of the binary diffusion couple consisting of almost pure materials A and B, which may form a single intermediate phase – α.
They have already found vast applications in materials joining, production of intermetallic compound foils and smart materials, in medical applications, military service, etc.

Third, changes in family composition and lifestyle promote changes in the use of space, construction techniques, and materials for traditional architecture, resulting in the loss of the original characteristics of traditional settlements.
In terms of preserving the Dong rural settlement, it is as serious as the changes in building materials and structure techniques.
However, changes in modern lifestyle have transformed the original homogeneous settlement continuum into hetero-buildings that feature different materials, construction techniques, and architectural forms (Fig. 9).
