During the pipe jacking construction, the bearing plates of jack need the support of great reactive force which is provided by the side-wall of the working shaft and the soil mass behind the wall. In the shallow pipe-jacking working shaft, the soil mass only can provide limited reactive force due to the small height of the soil mass behind the side-wall, which becomes the difficult point in the design and construction of the shallow pipe-jacking working shaft. This thesis takes the actual projects for the examples to introduce the construction technology of shallow pipe-jacking working shaft in details, including the construction key points like pre-grouting injection consolidation, ring beam construction method as well as reverse construction method.

In the process of construction, with the mixture ratio design and appropriate construction conditions of SAC asphalt concrete mixture, it can not only have dense gradation with typeIasphalt concrete which has good durability and small porosity with its skeleton dense structure, but also it can be compatible with typeIIasphalt concrete which has the ability to resist deformation and the depth of the surface structure. This paper is making an effective exploration on the construction technology and the mixing ratio design of SAC asphalt concrete with the aid of the authors construction test results of a certain highway construction.

This paper presents a comprehensive framework to manage the main risk events of highway construction pro­jects within three stages: (1) identification of potential risks; (2) assessment and prioritisation of identified risks based on fuzzy FMEA; (3) identification of appropriate response. The main criteria analysed for prioritising potential risk events are cost, time and quality which are quantified and combined using fuzzy AHP. A new expert system is suggested for identifying an appropriate risk response strategy for a risk event based on risk factor, control number and risk alloca­tion. The best response action for a risk event is then identified with respect to the same criteria using “scope expected deviation” (SED) index. The proposed methodology is demonstrated for management of risk events in a construction project of Bijar-Zanjan highway in Iran. For the risk event of “increase in tar price”, deviation from the target values of the criteria is analysed for business-as-usual state plus two risk response actions using SED index. The results show that the response action of “changing paving construction technology from asphalt pavement to RCC pavement” can success­fully cope with the risk event of “increase in tar price” and have the minimum deviation.

Highway is an important channel to connect regional economic development, and is an indispensable part of modern transportation system. In view of the extensive nature of highway cover space and the existence of diversified construction environment, climate and geological influence in highway construction, soft soil foundation is one of the more typical geological forms. With wide distribution in our country, seen as a big difficulty, highway construction technology and directly affect the quality of highway construction, cost, if not properly handled, will cause the soft soil foundation highway engineering structure is not stable, prone to accidents in use. In this paper, we study the treatment of soft soil foundation in highway construction, and put forward some reasonable Suggestions.
