With Substructural Analysis Method(SAM) and Windler foundation model of lateral reaction, an interaction analysis model of frame structure-pile foundation-soil under lateral load is established.

Conclusions the application of DSAK in lateral window maxillary sinus lifting could shorten the surgery time obviously with low membrane perforation rate and slighter postoperative reaction.

Instant reaction time of peroneus longus and brevis muscles was longer when lateral ankle ligament was injured.
