Introduction Non-quantification risk factors should be controlled at the construction site of the bridge, and the common non-quantification risk factors can be defined as the subjective controlled factors which can be influenced by human.
Therefore, it is very important to correctly understand the human error model during the bridge construction process and correctly analyze the reasons of the mistake caused by manual work, and which has great instruction to reveal the essence of the mistake caused by manual work and control the risk caused by manual work Factors Affecting Reliability of Manual Work.
In the cooperation work of the group, the individual will always show several properties including relative property, imitativeness, competitiveness and being complementary to each other.
The properties can improve the reliability of the personal and the work efficiency when managers are good at management, but if not, it may cause serious negative effect and reduce the reliability [6].
There are three main factors affecting risk of construction machine, which in includes human, state of machine and economical efficiency use of machine.

In order to find out the mechanical properties using BI testing, many theories and models have been proposed.
The difference in tensile properties was attributed due to local variation in dwell temperature and cooling rate that dictated the local microstructure and properties of heat affected zone.
Conclusions Automated Ball Indentation testing technique was successfully used to evaluate the gradients in the mechanical properties of the fusion zone, heat affected zone and base metals.

It is observed that tool diameter and tool rotational speed are most significant factors affecting tensile shear strength.
The mechanical properties of AA6082-O are given in Table 1 and chemical composition of AA6082-O is tabulated in Table 2.
Heat input is a major parameter affecting formation of intermetallic compound which affects the strength of the joint.
It is used as mathematical model for prediction of tensile shear strength in terms of control factors as well as noise factors.

Mechanical and physical properties of a unidirectional carbon fiber reinforced epoxy matrix (T700/3234) composite have been evaluated after being vacuum thermal cycled (133~413 K, 10-3 Pa) up to 300 cycles.
It is suggested that debonding of fiber/epoxy interface and post curing in matrix during vacuum thermal cycling should be responsible for evolvement of mechanical properties of the T700/3234 composite.
This study focus in revealing the effects of vacuum thermal cycling on mechanical properties of a unidirectional carbon T700 reinforced 3234 matrix composite and its related damage mechanisms.
Mechanical properties of the T700/3234 composite before and after thermal cycling were measured using an INSTRON 8872 type material test system.

Moreover, influence of factors on mechanical properties of the one-way BSS with the cooperation of the supporting structure is investigated.
The factors include grouting, support form, corrosion.
However, there has been little research on the mechanical properties of BSS during various construction stages.
So in this paper, taking the beam string structure in a practical project as the research object, firstly mechanical properties of a single BSS during the prestressing phase is studied, and then the mechanical properties of the one-way BSS under various load cases is explored with the cooperation of the supporting structure, finally such factors as grouting, support form, steel corrosion, affecting the mechanical properties of the one-way BSS with the cooperation of the supporting structure, are further analyzed.
Influencing factors Grouting.
