Its special engineering geological properties often lead to the problem of engineering accidents and geological disasters [1].
Accordingly, the occurrence of engineering accidents and geological disasters in laterite area depend on the particularity of laterite.
Therefore, the depth study the changes of iron oxides in laterite will explains the mechanism of the occurrence of engineering accidents and geological disasters in laterite area.
That is the important role to the prevention of engineering accidents and geological disasters in laterite area especially Yunnan area.
At present, the migration of material composition especially iron oxide in laterite lack research, but the iron oxide plays a key role to the particularity of laterite, because the migration of iron oxide in laterite directly affect the connection ability of laterite particles, and then affects the structure stability of laterite.

Summing up the above, in different engineering background, the joint stiffness was diversely, which surveyed by experiment or calculated by design models.
Connecting bolts between segments are the main part and key position in shield tunnel.

It is the key of analyzing pile foundation performance of bearing horizontal load to confirm counter-force coefficient of foundation soil.
Engineering investigation, earthwork in suit and laboratory test are adopted to analyze composition of the pile lateral soil and physico-mechanical properties for analyzing the capacity that pile foundation resisted horizontal load.
As an example of m method, horizontal resistance stiffness of pile lateral soil can be shown in Eq. 9: (9) Experimental study Engineering geological profile.
Soil basic situation on engineering site are saturated silt, Micronesia sand and lamp medium sand gravel according to the geological data.
This experiment combined with horizontal static load experiment of detailed engineering of Berlin's four season residential area of Qianguo county of Songyuan in Jilin province.
