Recommendations on Promoting the Landscape Architecture Esthetics Research in China Yan Long1,a, Rongke Jin2,b 1 School of Urban Design, Wuhan University, Wuhan, Hubei, China 2 School of Engineering and Architecture, Jiaxing University, Jiaxing, Zhejiang, China a 3775574@qq.com; b 43410897@qq.com Keywords: Habitat Environmental Science; Landscape Architecture; Landscape Architecture Esthetics; Landscape Esthetics Abstract: This article reviews the landscape esthetics research in China in the last thirty years by collecting and listing the domestic journals concerning landscape esthetics and related literature since 1980.
The research of landscape esthetics still stays in the phase of “pre-paradigm”, so it top priority is to develop its diagram. 2.2 Complexity in the extension of the theory Landscape esthetics, which applies esthetics as the basic principle, can reveal the esthetic characteristics through experience and appreciation, so that people can learn more about the research theories relating to the nature and humanistic picture, including substance, technology, engineering, art, economy, and many other aspects.
Landscape architecture discipline absorbs the theoretical achievements from the following disciplines extensively: geography, forestry, geology, sociology, art, public management, environmental science and engineering, civil engineering, hydraulic engineering, surveying and mapping science and technology.

A New Technique and Its Application in the Conservation of Historical Masonry Constructions ──underpinning by manual pipe-jacking ZHANG Weixi1,a, CHEN Ping1, ZHAO Dong 1 and ZHANG Yanqiang1 1 Department of Civil Engineering, Xi'an Univ. of Arch &Tech., Xi'an, China a zhwx4587@126.com Abstract: The structural damages, which result from the inadequate bearing capacity or the asymmetric support of foundation, are one of the crucial works in the conservation of historical masonry constructions.
The technique has been successfully used in some engineering of the conservation of historical masonry construction yet (Zhang et al. 2009, Xian et al. 2005), it is shown that this process has advantages in the field of masonry protection, but the basic problems involved in the process have not been studied yet.
Based on a practical engineering, the basic principles of the technique, the process of jacking and the calculation of jacking force are introduced in this paper, it may be benefit to the further study for this new structure protection technique.
Figs. 1, 2 show the jacking system and a practical engineering instance respectively
Front-end Resistance of the First Box Girder In order to reduce stratum loss caused the gap around the box girders, there is always "less digging"in practical engineering, so the face resistance can not be ignored.
