Abstract: Charmless three-body B decays offers a key probe for the properties of the weak interaction associated with quarks. In the experimental measurement, we can unfold the complicated decay structure over the multi-body phase space based on the Dalitz plot technique. We perform a study on the B+ -> pi+ pi0 pi0 decay by using the data sample collected at the Upsilon(4S) with Belle detector and KEKB asymmetric energy e+e- collider. This study includes the the measurement on the branching fraction and CP asymmetry of the inclusive B+ -> pi+ pi0 pi0 decay. By the sPlot tool, we also perform further study on structure of this decay with background-subtracted Dalitz plot, including the measurements of quasi-two-body modes such as B+-> rho(770)+ pi0 and other resonant states, and searching for localized CP asymmetry. Preliminary results will be reported.
